WebConclusions in a goodness-of-fit test. When Silvia feeds her cat, she places food in 3 3 different locations. She wondered if her cat was equally likely to eat first from each of the locations, so she tallied which location her cat chose first in a sample of 30 30 feedings. Here are the results along with a chi-square goodness-of-fit test:
where: F = the cumulative distribution function for the probability distribution being tested.; Y u = the upper limit for class i,; Y l = the lower limit for class i, and; N = the sample size; The resulting value can be compared with a chi-square distribution to determine the goodness of fit. The chi-square distribution has (k … See more The goodness of fit of a statistical model describes how well it fits a set of observations.

However, as the GoF cannot reliably distinguish valid from invalid models and since its applicability is limited to certain model setups, researchers should avoid its use as a goodness of fit measure. The GoF may be useful for a PLS multigroup analysis ...
WebIFI: the Incremental Fit Index (IFI) adjusts the Normed Fit Index (NFI) for sample size and degrees of freedom (Bollen's, 1989). Over 0.90 is a good fit, but the index can exceed 1. PNFI: the Parsimony-Adjusted Measures Index. There is no commonly agreed-upon cutoff value for an acceptable model for this index. http://www.davidakenny.net/cm/fit.htm
