The resulting scores of all the elected
goodness of fit test indicate a good model fit are shown in Table 8.
The data are presented in the form of percentages and the inferential statistics used were chi-square
goodness of fit test and z-test for proportions.
Chi-square
goodness of fit test was used for univariate analysis of all the ten nominal variables to determine the significance of their observed counts to the expected counts of their respective attributes, assuming that they have equal expected counts.
However, the
goodness of fit test Kolmogrove-Simernov (K-S) fit a continuous distribution, called Log-Logistic (three parameters) distribution (shown in Figure 2) at 99% and 98% level of significance, whereas Anderson Darling (AD) accepts it for 95% level of significance.
Chisquare
goodness of fit test was computed to review the isolation of MBL positive isolate considering P-value = 0.05 is statistically significant.
In comparative analysis, Chi- Square
goodness of fit test shows that Gumble Distribution gives better results as compared to Log Pearson Type III Distribution.
Goodness of fit test has been also used in this paper to identify the best fit models.

goodness of fit test for histograms regarding network traffic packet size process", in Proc.
In an attempt to choose the "best" probability model to describe the concentration of carbon monoxide in Lagos State for the period studied, Kolmogorov-Smirnov
goodness of fit test was conducted.
In both the chi-squared and the H-L
goodness of fit test, if the test statistic is not significant then the model represents an adequate fit, implying that the model predictions are not significantly different from observed values.
The primary purpose of this book is to provide a detailed exploration of the theory, methods, and applications of the chi-squared
goodness of fit test first advanced by Karl Pearson over 100 years ago.
