Comment (by Paul McClellan <paulm@…>):

 I have wrappers around boost:

 {{{

 #include <boost/math/distributions/logistic.hpp>

 double logistic_pdf( double dX, double dL, double dS )
 {
         // logistic distribution object:
         boost::math::logistic logis(dL, dS);
         return pdf(logis, dX);
 }

 double logistic_utp( double dX, double dL, double dS )
 {
         // logistic distribution object:
         boost::math::logistic logis(dL, dS);
         return cdf(complement(logis, dX));
 }

 }}}


 These test cases should error, but return 0.0:


 {{{
 logistic_pdf(Pc_PosInf, Pc_PosInf, 1.0);
 logistic_pdf(Pc_PosInf, 0.0, Pc_PosInf);
 logistic_pdf(Pc_PosInf, 0.0, 0.0);

 logistic_utp(Pc_PosInf, Pc_PosInf, 1.0);
 logistic_utp(Pc_PosInf, 0.0, Pc_PosInf);
 logistic_utp(Pc_PosInf, 0.0, 0.0);

 }}}
