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.

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
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.
