Webgoodfit essentially computes the fitted values of a discrete distribution (either Poisson, binomial or negative binomial) to the count data given in x. If the parameters are not specified they are estimated either by ML or Minimum Chi-squared.

WebMay 14, 2024 · A goodness-of-fit test is concerned with the question whether a data set may have been generated by a certain distribution. It has a null hypothesis of the form \(H_0: F=F_0\), where \(F_0\) is a probability distribution. For example, one might wish to test whether a data set comes from a standard normal distribution.
