WebJan 6, 2016 · The first plot depicts residuals versus fitted values. Residuals are measured as follows: residual = observed y – model-predicted y. The plot of residuals versus predicted values is useful for checking the assumption of linearity and homoscedasticity. WebHeteroscedasticity produces a distinctive fan or cone shape in residual plots. To check for heteroscedasticity, you need to assess the residuals by fitted value plots specifically. Typically, the telltale pattern for heteroscedasticity is that as the fitted values increases, the variance of the residuals also increases. cooney southWebThe predicted value of y ( ) is sometimes referred to as the fitted value and is computed as y ^ i = b 0 + b 1 x i . 687 Experts. ...
