loglikediw function

likelihood function

Log-likelihood function of the discrete inverse Weibull

loglikediw(x, q, beta)

Arguments

• x: a vector of sample values
• q: the value of the $q$ parameter
• beta: the value of the $\beta$ parameter

Returns

the value of the log-likelihood function (changed in sign) of the discrete inverse Weibull distribution with parameters $q$ and $\beta$ computed on a sample x

Examples

n<-100
q<-0.4
beta<-2
x<-rdiweibull(n, q, beta)
# loglikelihood function (changed in sign) computed on the true values
loglikediw(x, q, beta)
par<-estdiweibull(x, method="H")
par
# loglikelihood function (changed in sign) computed on the ML estimates
loglikediw(x, par[1], par[2])
# it should be smaller than before...
