If a residual/response output filename is specified by Residual file=, a file of residuals from the main calibration is produced. This file is designed for input into other programs with one line per measurable observation. It can be used for calculating other fit statistics and producing specialized diagnostic reports.
Heading lines= control the output of the heading line. CSV= allows tab-delimited and other formats. QM quotation marks, controls whether labels are within quotation marks.
This file can be produced from the Output Files menu by clicking on Residual/Response Output file. This has additional options.
Here is an example of the format. The precise format depends on the number of facets in your data:
Obs Stp Exp Res Var StRes Wt LProb Logit Labels
1 1 1.43 -.43 .38 -.70 1.00 -.8408 .99 1 1
2 2 1.54 .46 .34 .79 1.00 -.5353 1.30 1 2
1 1 1.09 -.09 .46 -.13 1.00 -.6288 .19 1 3
The fixed-format columns are: |
|
1-10 |
response as observed in the data file |
11-20 |
response as renumbered into a count of ordered steps |
21-30 |
expected score for this response |
31-40 |
score residual: (observed - expected) |
41-50 |
variance of expected score, the statistical information in this response |
51-60 |
standardized residual: residual / (variance) |
61-70 |
weighting (model weight * observation weight) |
71-80 |
natural logarithm of the probability of the observation |
81-90 |
logit sum of the measures producing the observation |
91-100 |
element number for facet 1 |
101-110 |
element number for facet 2 |
| |
|
..1-..0 |
element number for last facet |
