Problem Note 32529: Probability of Close Fit value is incorrect when the analysis has more than one group
 |  |  |  |
If you fit a Multiple-Group (multigroup analysis, multi-group analysis) model in PROC TCALIS (experimental), the Probability of Close Fit value will be incorrect.
*
For software releases that are not yet generally available, the Fixed
Release is the software release in which the problem is planned to be
fixed.
There are no warnings or errors to indicate that the value was computed incorrectly.
The following example demonstrates how to compute the correct value from the PROC TCALIS output.
Formula PROC TCALIS Fit Summary Example N N Observations 145 k number of groups in the analysis 2 dmin Chi-Square DF 24 fmin Fit Function 0.1576
data _null_;
N=145;
k=2;
dmin=24;
fmin=0.1576;
x=(N-k)*fmin;
lambda=((0.05)**2)*(N-k)*dmin/k;
p=1-cdf('chisquare',x,dmin,lambda);
put 'Probability of Close Fit ' p= 8.4;
run;
The SAS log will show:
Probability of Close Fit p=0.7488
