10.4 The Goodness-of-Fit Test – Introduction to Statistics
WebThe goodness-of-fit test is a well established process: Write down the null and alternative hypotheses. The null hypothesis is the claim that the categorical variable follows the hypothesized distribution and the alternative hypothesis is the claim that the categorical variable does not follow the hypothesized distribution. WebSep 22, 2011 · More formally, the chi-square goodness of fit test statistic can be defined as follows. For the chi-square goodness of fit, the data is divided into k bins and the test statistic is defined as \( \chi^{2} = \sum_{i=1}^{k}(O_{i} - E_{i})^{2}/E_{i} \) where O i is the observed frequency for bin i and E i is the expected frequency for bin i.
