WebA goodness-of-fit test, in general, refers to measuring how well do the observed data correspond to the fitted (assumed) model. We will use this concept throughout the course as a way of checking the model fit. Like in linear regression, in essence, the goodness-of-fit test compares the observed values to the expected (fitted or predicted) values. WebFeb 6, 2024 · fit The ﬁtted model from which the residuals were extracted. (Only required if what = "fitted" and object inherits from class "resid".) distribution Function that computes the quantiles for the reference distribution to use in the quantile-quantile plot. Default is qnorm which is only appropriate for models using a probit link function.
