I have found a difference between the results produced by SPSS and
SYSTAT in linear regression with no constant term. Below are the
results from the programs. As you can see the adjusted R2 given by the
2 programs is different. Which one is correct?
Data (from NIST line origin dataset):
Y X
130 60
131 61
132 62
133 63
134 64
135 65
136 66
137 67
138 68
139 69
140 70
Linear regression Y on X with no constant term.
SYSTAT:
R2 = 0.999365492
adj R2 = 0.999365492
SPSS:
R2 = 0.9993654922987
adj R2 = 0.9993020415285
I would appreciate some help.
Many thanks,
Dr L Green.
