(statistics)
The degree to which the observed frequencies of occurrence of events in an experiment correspond to the probabilities in a model of the experiment. Also known as best fit.

goodness of fit

Some criteria used with the purpose of evaluating performances of models studied were on the analysis of residual (The Runs test and Durbin Watson) and goodness-of-fit (Residual Mean Square, the coefficient of determination and F-ratio).
In comparing the fit of hypothesized models, chi-square tests and goodness-of-fit indexes were used.

In the first model (Stressors), it was hypothesized that the five categories (Frustrations, Conflicts, Pressures, Changes, Self-imposed) would adequately define the Stressors section (a summary of the relationships among all the variables studied on SSI are displayed in Figure 1 and a summary of the goodness-of-fit analyses are presented in Table 2).
The chi-square goodness-of-fit test indicates that both Models 1 and 2 fail to accurately reproduce the sample correlational data, but the Modified Oblique Five are markedly less discrepant in this regard.
The goodness-of-fit indexes for this model were also inadequate (see Table 1), with CFIs below the standard cut-off, especially for the sample of adults.
