WebGoodness of fit is what you should pay attention to if you think of the model as purely descriptive, as providing a summary of the data, rather than predictive.

WebSep 23, 2015 · The name suggests that the goodness of fit test is used to determine how well a model fits the data. But the linear model is already the 'best' fit since we have minimized the sum of the squared error terms. Why do we need to test 'goodness of fit' again? We know it is a good fit because we minimized the sum of the squared errors. … The goodness of fit of a statistical model describes how well it fits a set of observations. 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 … pokemon xy journey on netflix
