Statistical Models

Residual plots can be used to determine whether a particular model of correlation is the best model to fit the data. In general, a residual plot with points randomly scattered about the x-axis indicates that model chosen is the best fit for the data. A residual plot that shows a clear pattern indicates that the model chosen is not appropriate for the data.

Large residual values may also indicate that the model chosen is not appropriate.

Large residual values may also indicate that the model chosen is not appropriate.
