[Developers] Inverse gamma

[Mark Maunder]

Does anyone know if there is a version of the two parameter gamma
function?

 

Below are some undocumented functions  

 

df1b2fun.h:df1b2variable inv_cumd_gamma(const df1b2variable& _y,const
df1b2variable& _a);

df1b2fun.h:double inv_cumd_gamma(double y,double _a);

df1b2fun.h:df1b2variable norm_to_gamma(const df1b2variable & v,const
df1b2variable& alpha,

df32fun.h:  df3_two_variable cumd_gamma(const df3_two_variable& x,

df32fun.h:  df3_two_variable gammln(const df3_two_variable& xx);

fvar.hpp:dvariable inv_cumd_gamma(const prevariable& _y,const
prevariable& _a);

fvar.hpp:double inv_cumd_gamma( double _y,double _a);

fvar.hpp:dvariable cumd_gamma(const dvariable& x,const dvariable& a);

fvar.hpp:double cumd_gamma(double x,double a);

fvar.hpp:dvariable norm_to_gamma(const prevariable & v,const
prevariable& alpha,

fvar.hpp:double norm_to_gamma(double v,double alpha,double
bound=0.999999);
