Loglikelihood function (changed in sign) for the type 1 discrete Weibull distribution

1	loglikedw(par, x, zero = FALSE)

`par`	the vector of parameters, q and β
`x`	the vector of sample values
`zero`	`TRUE`, if the support contains 0; `FALSE` otherwise

the value of the loglikelihood function (changed in sign) for the observed sample x under the parameters par
