These can be used to evaluate different models and assign a numerical score to each model based on the goodness of fit
to the data and the number of parameters in the model.
Summary results of goodness of fit
criteria for data mining algorithms tested for estimating CCW trait are given in Table I.
On the other hand, Gbangboche, Glele-kakai, Salifou, Albuquerque, and Leroy (2008) compared the goodness of fit
of four non-linear growth models in West African Dwarf sheep and concluded that the Brody model provided the best fit.
Effort based SRGMs are more realistic and result in better goodness of fit
. Hence, some SRGMs with testing effort functions were proposed in the past.

Univariate analysis of the nominal variables in acute poisoning treated in medical ICU by Chisquare Goodness of Fit
Chi-square, SSE and SAE are other relative measures for comparing the goodness of fit
performance of estimated distributions models.
According to Child (2006), three common measures of overall goodness of fit
are a chi-square ([chi square]) measure, goodness of fit
index (GFI) and root mean square residual (RMR).
2006).There are several statistics used to determine the goodness of fit
. The model with smallest standard error of prediction is assumed to have the best fit to the data and in order that asymptotic weight values offered the best opportunity to make direct comparisons among all models (Brown et al.
It also explains how to evaluate the goodness of fit
of a linear regression model.

In the literature, various methods and criteria are proposed to establish the goodness of fit
of a model depending on the type of model.
