WebA residual plot shows the residuals on the vertical axis and the independent variable on the horizontal axis. If the points are randomly dispersed around the horizontal axis, a linear regression model is appropriate for the data; otherwise, a non-linear model is more appropriate.

For a location-scale model with distribution W, CDF ^ ( T j X j) can be calculated from the standardized residuals. s j = f ( T j) − X j ′ β ... franchement bee
