+[ Overview ]
+
+This package implements the derivative version of the adaptive rejection
+sampler (Gilks, 1992).
+
+A tool for testing is provided for standard distributions, which makes use of
+their known cdf to produce kolmogorov-smirnov statistics.

+@article{citeulike:3015268,
+ abstract = {We propose a method for rejection sampling from any
+ univariate log-concave probability density function.
+ The method is adaptive: as sampling proceeds, the rejection envelope
+ and the squeezing function converge to the density function.
+ The rejection envelope and squeezing function are piece-wise exponential
+ functions, the rejection envelope touching the density at previously
+ sampled points, and the squeezing function forming arcs between those
+ points of contact. The technique is intended for situations where
+ evaluation of the density is computationally expensive, in particular
+ for applications of Gibbs sampling to Bayesian models with non-conjugacy.
+ We apply the technique to a Gibbs sampling analysis of monoclonal
+ antibody reactivity.},

+[ Overview ]
+
+ These are C++ tools that pertain to the need to transform a binary sequence
+ to a sequence of tuples (pairs) and vice versa. This need arises in
+ statistics where the data consists of a set covariates, and a set of
+ responses.
+
+[ Notation ]
+
+ A pair is called a tuple with a head and tail components.
+
+[ Compiler ]

+
+[ Overview ]
+
+These are C++ classes that bridge a distribution type (D) defined in boost::math
+to a class type (Rd) that models RandomDistribution. For example,
+
+ generate_n(b_x, n,dist, urng);
+ sample(dist,urng)
+
+[ Useful links ]
+
+http://www.boost.org/doc/libs/1_35_0/libs/math/doc/sf_and_dist/html/index.html
+http://www.boost.org/doc/libs/1_39_0/libs/random/index.html
+
+[ meta ]
+
+ A metafunction that map a distribution to a type (or related traits) that
+ model RandomDistribution.
+
+[ distributions ]
+
+ Specializes dist_random for each distribution (normal, exponential etc.).
+
+[ functional ]
+
+ check_convergence<T> Checks agreement between the distribution and its
+ random counterpart based using a kolmogorov-smirnov
+ methodology.
+[ random ]
+
+ Function templates that sample from the distribution
+ generate_n(b_x, n,dist, urng);
+ sample(dist,urng)
+ The actual random generator is hidden in the implementation. These functions
+ are conditioned on is_scalar_dist<D> to avoid ambiguity (SFINAE) with a
+ similar interface defined in joint_dist.
+

+[ Overview ]
+
+These C++ classes mirror sandbox/statistics/scalar_dist but in the multivariate
+framework.
+
+[ Compiler ]
+
+gcc version i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1
+
+[ Dependencies ]
+
+/usr/local/boost_1_39_0/
+/sandbox/statistics/arithmetic/
+/sandbox/statistics/dist_random
+/sandbox/statistics/mpl/
+/sandbox/statistics/scalar_dist/
+/sandbox/statistics/standard_distribution/
+/sandbox/statistics/vector_space/
+
+[ Bugs ]
+
+A possible bug is described in example_1.cpp
+
+[ History ]
+
+July 2009 : Current version
+
+[ distributions ]
+ Collects hpp files pertaining to a given distribution
+
+[ distribution ]
+
+ Defines a distribution and possibly associated functions
+ (log_unnormalized_pdf). Currently:
+ iid
+ independent
+
+[ fun_wrap ]
+
+ Similar to fun_wrap in scalard_dist
+
+[ meta ]
+
+ Similar to meta in scalard_dist.
+
+ is_joint_dist is used to manage the overload set non-intrusively (SFINAE),
+ by client libraries, where either a scalar or a joint distribution is a
+ valid argument to a function template.
+
+[ random ]
+
+ Let b_x point to the beginning of a range of scalars
+ Let b_row point to beginning of a range of ranges of scalars.
+
+ sample(b_x,joint,urng);
+ generate_n(b_row,n,joint,urng);
+
+[ unscope ]
+
+ A version of pdf, cdf etc., defined in scope boost that forwards to that
+ in scope boost::joint_dist.
+
+ The rationale for this, is that some function templates in other libraries
+ in sandbox/statitics apply to scalar and joint distributions alike, and
+ therefore require a common interface.

+
+[ History ]
+
+July 2009 : Current version
+March 2009: improved_fast_gauss_transform is now deprecated
+
+[Design]
+
+Let h denote bandwidth, d dimension, ||.|| norm.
+
+To perform density or conditional mean estimation, we are interested in
+operations that involve an abitrary bandwidth binary kernel, K[h](x0,x1),
+and/or possibly its multivariate extension K[d,h](x0,x1).
+
+Our design rests on the following relationships (see [Math representation])
+ - standardized kernel (bandwidth = 1) and kernels indexed by a bandwidth
+ - unary kernels, K(x), and binary kernels, K(x0,x1)
+ - univariate and multivariate kernels.
+
+The client need only specify the standardized kernel, such as
+scalar::gaussian, while a crtp mechanism, implemented in scalar::crtp,
+adds the remaining functionality.
+
+The class template kernel::multi, parameterized by an arbitrary unavariate
+kernel provides a multivariate analogue to the latter.
+
+The classes rp_visitor and nw_visitor are implementations for the Rosenblatt-
+Parzen and Nadaraya-Watson estimators for a given test value, x.
+
+Iterating either of the above estimators over a training sample is implemented
+by kernel::estimator, which, in turn, can be used in a std::for_each construct
+to iterate over test data.
+
+Bandwidth selection for density estimation is provided by
+bandwith::normal_distribution.
+
+[TODO]
+
+- Bandwidth selection by cross validation and other methods.
+- Provide a IFGT version of the above (see our deprecated
+improved_fast_gauss_transform package)
+- Kernel regression etc.
+
+[Math representation]
+
+Univariate
+ Unary:
+ Unnormalized: Ku(x) : [0,inf) -> [0,inf)
+ Normalized: K(x) : [0,inf) -> [0,1)
+ K(x) = Ku(x) / c such that integral K(x) dx = 1
+ Parameterized
+ by bandwidth K[h](x) = K(x/h) / h
+
+ e.g.
+ Ku(x) : exp(-x^2/2)
+ c : sqrt(2 pi)
+ K(x) : exp(-x^2/2) / sqrt(2 pi)
+ K[h](x) : exp(-(x/h)^2 /2) / ( sqrt(2 pi) * h)
+
+Binary:
+ K(x0,x1) = K(|x0-x1|)
+
+Multivariate:
+ Ku[d](x) : Ku(||x||)
+
+ e.g
+ Ku[d](x) : exp(-||x||^2) : Ku(||x||)
+ c[d] : (sqrt(2 pi))^d : c^d
+ K[d](x) : Ku[d](x)/c[d]
+
+ K[d,h](x) : exp(-||x/h||^2)/(c * h)^d
+ = Ku(||x||/h) / (c * h)^d

+[ Overview ]
+
+This C++ package contains
+
+i) Wrappers are individual or bundled references to quantities such as data,
+parameters and model abstractions, that arise in frequentist or Bayesian
+modeling. They give explicit meaning to the above quantities and simplify the
+syntax of functions that takes these quantities as arguments.
+
+ii) STL-like algorithms for computing likelihoods or posterior distributions,
+by aggretating the contributions of data-units in an (for now) iid setting.
+
+Examples can be found in statistics/survival/libs/example
+
+[ Compiler ]
+
+gcc version i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1
+
+[ Dependencies ]
+
+/boost_1_39_0/

+/sandbox/statistics/binary_op/
+
+[ History ]
+
+July 2009 : Current version
+
+[ Notation ]
+
+LPdf and Model are concepts defined within this package.
+
+ Type Object Abstraction Concept
+ name name
+ - T t scalar is_scalar
+ - X x covariate
+ - Y y response
+ - P p parameter
+ - D d prior distribution LPdf
+ - M m likelihood model Model
+ - Rx rx covariates ForwardRange
+ - Ry ry responses ForwardRange
+ - O o OutputIterator
+
+Note that X, Y, P are not retricted to scalars. For example,
+ X == std::vector<T>
+ Y == survival::data::event<T>
+
+ Class Alias Object name
+ model_parameter_<M,P> mp_ mp
+ model_dataset_<M,Rx,Ry> md_ md
+ prior_model_dataset_<D,M,Rx,Ry> pmd_ pmd
+
+[b_x,e_x) and [b_p,e_p) denote iterator ranges to covariates and
+parameter values, respectively.
+
+[ Concepts ]
+
+- Model
+ m models Model iff
+ Expression Return type
+ log_likelihood(make_model_data(m,x,y),p) T
+- LPdf
+ d models LPdf iff
+ Expression Returns
+ log_unnormalized_pdf(d,p) T
+
+Those D such that is_scalar_dist<D> or joint_dist<D> evaluates to true model
+LPdf. Check directory unscope in either package.
+
+[ wrap ]
+ Example of wrappers:
+ md_ md(m,rx,ry);
+ md.covariates();
+
+ Often we only need a temporary, in which case it is preferable to call an
+ associated creator function that deduces the types of its arguments:
+ make_model_dataset(m,rx,ry);
+
+[ functional ]
+ Functors that support [ algorithm ]
+
+[ algorithm ]
+ Iterate over a dataset or parameter values to produce a likelihood or
+ set of likelihood (or posterior) values
+
+ Expression Return type
+ log_likelihood(mp,b_x,e_x,b_y) T
+ log_likelihoods(md,b_p,e_p,o) O
+ log_posteriors(pmd,b_p,e_p,o) O
+
+[ TODO ]
+
+- Some simple examples.
+- Check integration with Boost.Probability i.e. T = boost::log_likelihood
+- Think about non-iid
+- Think about derivatives.

+ // Background:
+ // \see http://mathworld.wolfram.com/Polynomial.html
+ // A polynomial is a mathematical expression involving a sum of powers in
+ // one or more variables multiplied by coefficients. A polynomial in one
+ // variable (i.e., a univariate polynomial) with constant coefficients is
+ // given by
+ // a_nx^n+...+a_2x^2+a_1x+a_0. (1)
+ // The individual summands with the coefficients (usually) included are
+ // called monomials (Becker and Weispfenning 1993, p. 191),
+ // the products of the form x_1^(alpha_1)...x_n^(alpha_n)
+ // in the multivariate case,
+ // i.e., with the coefficients omitted, are called terms
+ // (Becker and Weispfenning 1993, p. 188).
+ // The highest power in a univariate polynomial is called its order,
+ // or sometimes its degree
+
+
+ // Example :
+ // variables = (a,b,c)
+ //
+ // 1
+ // >a >b >c
+ // >a^2 ab ac >b^2 bc >c^2
+ // >a^3 a^2b a^2 c ab^2 abc ac^2 >b^3 b^2c bc^2 > c^3
+ //
+ // each > above marks the begining of a "read range"
+ // the kth write range on the nth line is obtained by
+ // multiplying the kth read range on the (n-1)th line
+ // by the kth variable in (a,b,c)
+ // For example, (b^3, b^2c, bc^2) = b*(b^2, bc, c^2)

+
+[ Overview ]
+
+These are C++ classes that extend boost/math/distributions by providing
+
+ - wrappers that decouple the function, such as pdf, from the distribution
+ to which it is applied.
+ - algorithms that iterate over inputs
+ - mappings of distribution functionals (pdf->1/pdf)
+
+[ Useful links ]
+
+http://www.boost.org/doc/libs/1_35_0/libs/math/doc/sf_and_dist/html/index.html
+
+[ unscope ]
+
+ pdf, cdf etc. are defined in scope boost::math. Unscope creates a version
+ defined in scope boost that forwards to that in boost::math.
+
+ The rationale for this, is that some function templates in other libraries
+ in sandbox/statitics apply to scalar distribution and joint distributions
+ alike, and therefore require a common interface.
+
+[ fun_wrap ]
+
+ Decouples the function, such as pdf, from the distribution D:
+ fun_wrap::cdf_<D>::instance
+
+[ algorithm ]
+
+ Thanks to fun_wrap, we can parameterize algorithms as follows:
+ accumulate<fun_wrap::cdf_>(dist,b_x,e_x);
+ transform<fun_wrap::cdf_>(dist,b_x,e_x,b_f);
+
+[ map_pdf ]
+
+ Compare a hypothetical function:
+ inverse_pdf(dist,x)
+ to
+ pdf(make_inverse_pdf(dist))
+ The second form, used here, is more economical because we can reuse the
+ functionality associated with pdf, such as fun_wrap::pdf_. It is also
+ straightforward to combine mappings:
+ Expression: Result type
+ make_ratio_pdf(a,b) product_pdf<A,inverse_pdf<B> >
+ Usage:
+ pdf(make_ratio_pdf(a,b),x)
+
+
+[ meta ]
+
+ - signature, pointer and delegate are behind fun_wrap's implementation
+ - The meta-functions
+ is_scalar_dist
+ has_pdf
+ distinguish between distributions and objects that aren't but share their
+ functionality (such as those in map_pdf).
+
+ They are used to manage the overload set non-intrusively (SFINAE), by client
+ libraries, where both scalar and joint dists are valid arguments to
+ a function template.
+
+[ Compiler ]

+gcc version i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1
