Standardized Residuals Plot

The Standardized Residuals plot is useful for determining the adequacy of the life-stress model for the current data. The plot line has a mean of zero and negative values are possible. The appropriate probability transformation is plotted on the y-axis and the value of the residual is plotted on the x-axis. The plotted points (residuals) are based on the data, which are transformed using an appropriate transformation based on the selected life-stress model. If the model adequately fits the data, the points should track the plot line.
