Sorted by: 11. The goodness-of-fit test based on deviance is a likelihood-ratio test between the fitted model & the saturated one (one in which each observation gets its own parameter). Pearson's test is a score test; the expected value of the score (the first derivative of the log-likelihood function) is zero if the fitted model is ...

Measures of goodness of fit typically summarize the discrepancy between observed values and the values expected under the model in question. Such measures can be used in statistical hypothesis testing, e.g. to test for normality of residuals, to test whether two samples are drawn from identical distributions (see Kolmogorov–Smirnov test), or whether outcome frequencies follow a specified … oversight insightsWebThis unit will calculate the value of chi-square for a one-dimensional "goodness of fit" test, for up to 8 mutually exclusive categories labeled A through H.
