Hi,

 

I am using the  function "dinvgamma(sigma, shape, scale)".

 

I would like to know the exact paramtetric distribution of this function please.

 

I checked R-help, it has the exact paramteric distribution for "dgamma", but i was not able to find those

corresponding to "dinvgamma".

 

'dgamma' is using the same parameter specification as the know gamma distribution.

However, when i assumed that 'dinvgamma' is having the same parameter specification as the know inverse gamma distribution, i got strange results.

 

Thanks for your support.

Regards,

 

Nabil.M
