WebSep 20, 2014 · Figure 1 – Chi-square test. Note that the “two-tailed” hypothesis is tested by a one-tailed chi-square test. Goodness-of-fit for two outcomes. Let obs 1 = number of observed successes and obs 2 = number of observed failures in n trials. Furthermore, let exp 1 = number of expected successes and exp 2 = number of expected failures in n trials.
WebA different approach to assessing the fit of a model and for comparing competing 2models is based on measures of information. As the multiplicity of Pseudo R statistics suggests, there is considerable controversy as to which (if any) of these measures should be used.
