A better plot may result from copying Facets graph coordinates, see "Copy Plot Data to Clipboard".

 

From the Output Files menu, "Graph output file" provides the values plotted in Table 8 for the probability curves and expected score ogive. Also produced by Graphfile=.

 

 

For help with this dialog box, see Output Dialog Box.

 

The output is in fixed column format or, if comma-separated values are preferred, specify "filename, CSV" or CSV=Y. For Tab-separated values, specify "filename, Tab" or CSV=Tab

 

Output to SPSS, Excel and R Statistics are in their native-format. Excel and R Statistics are launched.

 

Heading lines= controls display of heading lines. QM quotation marks, controls whether labels are withing quotation marks.

 

Modify Specifications provides further options

 

The fixed column format is:

 

 

    Scale   Measure  Expected    ExpCat    Prob:1    Prob:2    Prob:3    Prob:4    Prob:5    Prob:6    Prob:7    Prob:8    Prob:9

        1   -6.0000    1.0307         1     .9697     .0299     .0004     .0000     .0000     .0000     .0000     .0000     .0000

        1   -5.9880    1.0311         1     .9693     .0303     .0004     .0000     .0000     .0000     .0000     .0000     .0000

Example:Provide coordinates so I can plot beautiful probability curves using my graphics package:

Graphfile=plot.dat,CSV; the name of an output file with comma-separated values, produces, for a 3 category rating scale (or partial credit):

 

1,-2.00,.23,0,.79,.20,.01

1,-1.92,.24,0,.77,.21,.02

1,-1.85,.26,0,.76,.22,.02
