Enis,
The Unstandardized Predicted Value and the Standardized Predicted Value have
a perfect correlation because they are simple linear transformations of one
another. Illustrattively, the standardized predicted value involves the
subtraction of a constant (the mean predicted value) from each predicted
value, and division by a constant (the standard deviation of the predicted
values).
The adjusted predicted value is somewhat more complicated. This is the
predicted value for a case when it is excluded from the computation of the
regression coefficients.
HTH,

Dear list
I hope this email finds you all well on this late Friday afternoon.
Quick question:
I ran a simple regression and saved Unstandardized Predicted Value;
Adjusted Predicted Value; and Standardized Predicted Value
What is the difference between Unstandardized Predicted Value and
Adjusted Predicted Value?
I get almost identical values on these variables, correlation = 1.00
almost however they are not necessarily 100% equal.
Any ideas?
Enis
