-<li>
- I'm a FORTRAN/NAG/SPSS/SAS/Cephes/MathCad/R user and I don't
- see where the functions like dnorm(mean, sd) are in Boost.Math?
- Nearly all are provided, and many more like mean, skewness, quantiles,
- complements ... but Boost.Math makes full use of C++, and it looks a
- bit different. But do not panic! See section on construction and the
- many examples. Briefly, the distribution is constructed with the parameters
- (like location and scale) (things after the | in representation like
- P(X=k|n, p) or ; in a common represention of pdf f(x; μσ2). Functions like
- pdf, cdf are called with the name of that distribution and the random
- variate often called x or k. For example, <code class="computeroutput">normal
- my_norm(0, 1); pdf(my_norm, 2.0);</code>
- 
- </li>
-<li>
- I'm a user of <a href="http://support.sas.com/rnd/app/da/new/probabilityfunctions.html" target="_top">New
- SAS Functions for Computing Probabilities</a>. You will find
- the interface more familar, but to be able to select a distribution (perhaps
- using a string) see the Extras/Future Directions section, and /boost/libs/math/dot_net_example/boost_math.cpp
- for an example that is used to create a C# utility (that you might also
- find useful): see <a href="http://sourceforge.net/projects/distexplorer/" target="_top">Statistical
- Distribution Explorer</a> .
- </li>
-<li>
- I'm allegic to reading manuals and prefer to learn from examples. 
- Fear not - you are not alone! Many examples are available for functions
- and distributions. Some are referenced directly from the text. Others
- can be found at \boost_latest_release\libs\math\example. If you are a
- Visual Studio user, you should be able to create projects from each of
- these, making sure that the Boost library is in the include directories
- list.
- </li>
-<li>
- How do I make sure that the Boost library is in the Visual
- Studio include directories list? You can add an include
- path, for example, your Boost place /boost-latest_release, for example
- <code class="computeroutput">X:/boost_1_45_0/</code>
- if you have a separate partition X for Boost releases. Or you can use
- an environment variable BOOST_ROOT set to your Boost place, and include
- that. Visual Studio before 2010 provided Tools, Options, VC++ Directories
- to control directories: Visual Studio 2010 instead provides property
- sheets to assist. You may find it convenient to create a new one adding
- \boost-latest_release; to the existing include items in $(IncludePath).
- </li>
-<li>
- I'm a FORTRAN/NAG/SPSS/SAS/Cephes/MathCad/R user and I don't
- see where the properties like mean, median, mode, variance, skewness
- of distributions are in Boost.Math? They are all available
- (if defined for the parameters with which you constructed the distribution)
- via <a class="link" href="../dist/dist_ref/nmp.html#math.dist.cdf">Cumulative Distribution Function</a>,

- </li>
-<li>
- I am a C programmer. Can I user Boost.Math with C? 
- Yes you can, including all the special functions, and TR1 functions like
- isnan. They appear as C functions, by being declared as "extern
- C".
- </li>
-<li>
- I am a C# (Basic? F# FORTRAN? Other CLI?) programmer. Can I
- use Boost.Math with C#? Yes you can, including all
- the special functions, and TR1 functions like isnan. But you must build the Boost.Math as a dynamic library (.dll) and
- compile with the /CLI option. See the boost/math/dot_net_example
- folder which contains an example that builds a simple statistical distribution
- app with a GUI. See <a href="http://sourceforge.net/projects/distexplorer/" target="_top">Statistical
- Distribution Explorer</a> 
- </li>
-<li>
- What these "policies" things for? 
- Policies are a powerful (if necessarily complex) fine-grain mechanism
- that allow you to customise the behaviour of the Boost.Math library according
- to your precise needs. See <a class="link" href="../policy.html" title="Policies">Policies</a>.
- But if, very probably, the default behaviour suits you, you don't need
- to know more.
- </li>
-<li>
- I am a C user and expect to see global C-style<code class="computeroutput">::errno</code>
- set for overflow/errors etc? You can achieve what you
- want - see <a class="link" href="../policy/pol_ref/error_handling_policies.html" title="Error Handling Policies">error
- handling policies</a> and <a class="link" href="../policy/pol_tutorial/user_def_err_pol.html" title="Calling User Defined Error Handlers">user
- error handling</a> and many examples.
- </li>
-<li>
- I am a C user and expect to silently return a max value for
- overflow? You (and C++ users too) can return whatever
- you want on overflow - see <a class="link" href="error_handling.html#overflow_error">overflow_error</a>
- and <a class="link" href="../policy/pol_ref/error_handling_policies.html" title="Error Handling Policies">error
- handling policies</a> and several examples.
- </li>
-<li>
- I don't want any error message for overflow etc?
- You can control exactly what happens for all the abnormal conditions,
- including the values returned. See <a class="link" href="error_handling.html#domain_error">domain_error</a>,
- <a class="link" href="error_handling.html#overflow_error">overflow_error</a> <a class="link" href="../policy/pol_ref/error_handling_policies.html" title="Error Handling Policies">error
- handling policies</a> <a class="link" href="../policy/pol_tutorial/user_def_err_pol.html" title="Calling User Defined Error Handlers">user
- error handling</a> etc and examples.
- </li>
-<li>
- My environment doesn't allow and/or I don't want exceptions.
- Can I still user Boost.Math? Yes but you must customise
- the error handling: see <a class="link" href="../policy/pol_tutorial/user_def_err_pol.html" title="Calling User Defined Error Handlers">user
- error handling</a> and <a class="link" href="../policy/pol_ref/policy_defaults.html" title="Using Macros to Change the Policy Defaults">changing
- policies defaults</a> .
- </li>
-<li>
- The docs are several hundreds of pages long! Can I read the
- docs off-line or on paper? Yes - you can download the
- Boost current release of most documentation as a zip of pdfs (including
- Boost.Math) from Sourceforge, for example https://sourceforge.net/projects/boost/files/boost-docs/1.45.0/boost_pdf_1_45_0.tar.gz/download.
- And you can print any pages you need (or even print all pages - but be
- warned that there are several hundred!). Both html and pdf versions are
- highly hyperlinked. The entire Boost.Math pdf can be searched with Adobe
- Reader, Edit, Find ... This can often find what you seek, a partial substitute
- for a full index.
- </li>
-<li>
- I want a compact version for an embedded application. Can I
- use float precision? Yes - by selecting RealType template
- parameter as float: for example normal_distribution<float> your_normal(mean,
- sd); (But double may still be used internally, so space saving may be
- less that you hope for). You can also change the promotion policy, but
- accuracy might be much reduced.
- </li>
-<li>
- I seem to get somewhat different results compared to other
- programs. Why? We hope Boost.Math to be more accurate: our
- priority is accuracy (over speed). See the section on accuracy. But for
- evaluations that require iterations there are parameters which can change
- the required accuracy. You might be able to squeeze a little more accuracy
- at the cost of runtime.
- </li>
-<li>
- Will my program run more slowly compared to other math functions
- and statistical libraries? Probably, thought not always, and
- not by too much: our priority is accuracy. For most functions, making
- sure you have the latest compiler version with all optimisations switched
- on is the key to speed. For evaluations that require iteration, you may
- be able to gain a little more speed at the expense of accuracy. See detailed
- suggestions and results on <a class="link" href="../perf.html" title="Performance">performance</a>.
- </li>
-<li>
- Where are the pre-built libraries? Good news
- - you probably don't need any! - just #include <boost/math/distribution_you_want>.
- But in the unlikely event that you do, see <a class="link" href="building.html" title="If and How to Build a Boost.Math Library, and its Examples and Tests">building
- libraries</a>.
- </li>
-<li>
- I don't see the function or distribution that I want.
- You could try an email to ask the authors - but no promises!
