Description

Maximum likelihood fitting function for generalized logistic distribution.

Usage

1
parglo.maxlik(x, ini)

Arguments

x

vector of quantiles for which to evaluate the PDF.

ini

a vector of initial values of the parameters to be fit.

Details

This function is used internally by spei and spi and is supposed to never be needed by the regular user. Initial values for maximum likelihood estimation can be provided by parglo.

Value

a list of parameters of a generalized Logistic distribution function
