Hello all,
Does anyone know what might cause a gap in the middle of a residuals plot?
(predicted values plotted against residuals)
I'm guessing it could be one of two things - a range of outcome values
that never occur, or a range of predictor varibles that never occur,
possibly caused by combining two data sets measuring variables that have
very different ranges?
Hmmm.....
Any thoughts welcome! Thanks in advance,
Brian
