checking goodness of fit for Gompertz distribution in R -

-

i know how check weibull , exponential using fitdistr , ks.test.

but don't work gompertz.

i think need use maxlik , rgompertz , ks.gompertz don't understand how use maxlik find estimates of alpha , theta.

i found in maxlik pdf:

estimate parameter of exponential distribution

t <- rexp(100, 2)  loglik <- function(theta) log(theta) - theta*t  gradlik <- function(theta) 1/theta - t  hesslik <- function(theta) -100/theta^2  estimate analytic gradient , hessian  <- maxlik(loglik, gradlik, hesslik, start=1)  summary( )

how change gompertz?
