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 ... WebThe standardized residual is found by dividing the difference of the observed and expected values by the square root of the expected value. Standardized residual = O - E / √E The standardized residual can be interpreted as any standard score. The mean of the standardized residual is 0 and the standard deviation is 1.
