TRPOTYPE= transposing specifications

TRPOTYPE= controls the format of the transposed file written to TRPOFILE=. Details are given at Transpose file specifications.

Transposing switches around the rows and the columns in the Winsteps control and data file.

 

TRPOTYPE= has three characters:

 

First Character: The response-level data are:

O = Original data: data codes are those in the data file.

S = Scored data: data after applying NEWSCORE=, IVALUE=, KEY=, etc.

R = Recounted data: the data recounted upwards from 0 after applying STKEEP=No, etc.

 

Second Character: Deleted and deselect persons and items are: (IDFILE=, IDELETE=, ISELECT=, PDFILE=, PDELETE=, PSELECT=)

S = Squeezed out: deleted and deselected items and persons are omitted from the transposed file.

M = Missing data: deleted and deselected items and persons remain in the transposed file, but all their responses are indicated as missing data, "."

 

Third Character: Output:

B = Both Control and Data file: the transposed file can be analyzed. Additional control instructions may be required in the control section in order for the analysis to proceed correctly.

C = Control file only: Only the control file for the transposed data is output. The transposed data are not output.

D = Data file only: Only the transposed data are output. The control instructions are not.

 

Example: Transpose the multiple choice data after rescoring.

TRPOFILE = transposed-file.txt

TRPOTYPE = SMD ; Scored data, Missing data codes for deletions, Data only

 

Example: Use transposed files to display person response functions (= model and empirical ICCs).
