Pearson residuals

WebThe Pearson goodness of fit statistic (cell B25) is equal to the sum of the squares of the Pearson residuals, i.e. This can be calculated in Excel by the formula =SUMSQ (X4:X18). We can use P to test the goodness of fit, based on the fact that P ∼ χ2(n–k) when the null hypothesis that the regression model is a good fit is valid. WebThe Pearson statistic is a quadratic form alternative to the residual deviance, and is often preferred over the residual deviance because of its moment estimator character. The expected value of the Pearson statistic depends only on the first two moments of the distribution of the y i and in this sense the Pearson statistic is robust against

A goodness-of-fit test, in general, refers to measuring how well do the observed data correspond to the fitted (assumed) model. We will use this concept throughout the course as a way of checking the model fit. Like in linear regression, in essence, the goodness-of-fit test compares the observed values to the ...
