Standardized log residual

The log residual divided by its (asymptotic) standard error. Minitab calculates the standardized log residuals using the method you select to analyze the variability of your model. If you use the least squares estimation method, the standardized log residuals are the standardized residuals obtained from performing weighted least squares regression on the log of the standard deviation of your response. Use standardized log residual in residual plots to examine your model.
