Hi All

 

I have a data frame called "nbd" with two columns (x and  T). Based on this
dataset I want to find the parameters of a distribution with the following
log-liklihood function and with r and alpha as its parameters:

log(gamma(nbd$x+r))-log(gamma(r))+r*log(alpha)-(r+nbd$x)*log(nbd$T+alpha)

the initial value for both parameters is 1.

 

I would be thankful if you could help me to solve this problem in R.

 

Regards,

 

Ali
