Residuals / Responses Output File = " "

Up  Previous  Next

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
