PKMAP= customize Table 36 diagnostic maps

PKMAP= can be used to customize Table 36 diagnostic maps. These maps are based on the KIDMAP - www.rasch.org/rmt/rmt82k.htm

 

PKMAP= customization

Figure: PKMAP field numbers and positions

 

Format in Winsteps control file:

PKMAP=*    ; inline instructions for the PKMAP output in Table 36

(Field number)= value

....

*

 

PKMAP Size

The internal height of PKMAP grid box is 61 or MAXPAG= value - 8.

The internal width of the PKMAP grid box is LINELENGTH= value - 6.

 

Format in text file:
use Edit menu

Edit/Create file with NOTEPAD to modify these settings.

In text file, for example:

1D = Yes

Save text file as MyPKMAP.txt in the same folder as the Control file

Specification menu: PKMAP = MyPKMAP.txt

 

Field code

Values

Meaning

1T-9T = Top headings

1HY, 1H, 1HN = High side of grid

1M = Measure = Middle (ability)

1LY, 1L , 1LN = Low side of grid

1B-9B = Bottom footers

1E-5E = Color explanations

display the text in the field location

#nnn# (can be included in text)

display the statistic in the field location

1R = Response = Rating

(blank) or text or #nnn#

#CODE#

#CAT#

(as above)

Response code in the data file

Scored category number

1G = Grid for PKMAP layout

Top left cell of grid is:

HY High measure, Yes reached

HN High measure, Not reached

LY Low measure, Yes reached

LN Low measure, Not reached

Controls layout of the PKMAP by identifying the top left quadrant

1C-5C = Color codes

HTML color codes, e.g.,

light-green

#E7C4A3

The color codes for text in the grid cells:

1C = High Yes (Current level)

2C = High No (Next level)

3C = 50-50

4C = Low Yes (Current level)

5C = Low No (Next level)

1P = Placement of response

T = Rasch-Thurstone 50% threshold

H or F = Half-point and Full-point thresholds

Vertical measure at which to place a response.

1D = Display all the field numbers

"Y" = Display field numbers and values at start of output

The field codes and their values

1F = Minimum mean-square to report

0 = all mean-squares

1.5 = only persons with infit or outfit mean-squares greater than 1.5 are reported

Selects only Kidmaps for misfitting response strings

1S = Sort instructions

n = Entry number descending

N = Entry number ascending

m = Measure descending

M = Measure ascending

f = Mean-square fit descending

F = Mean-square fit ascending

fI, FI = use Infit mean-square
fO, FO = use Outfit mean-square
fB, FB = use bigger of both mean-squares

a = Alphabetical label descending

A = Alphabetical label ascending
a$S3W10, A$S3W10 = Alphabetical sort on part of person label

Order of the PKMAP Kidmaps in the output table.

1V-9V = Criterion lines

numbers followed by L or U

logit L or uscale U values for horizontal = lines on grid

Field number not in PKMAP= list

none

(ignored)

Control variable=

PSELECT=???A ; selection

PDELETE=(list of entry numbers)

PDFILE=(file of entry numbers)

ASCII=Webpage

HTML codes can be used with \< and \> replacing < and >. HTML codes are ignored for text output.

Color: \<font color=red\>....\</font\> for HTML colors
or \<span class=1C\>....\</span\> for the colors defined in 1C, 2C, 3C, 4C, 5C

A list of color names is shown at http://www.w3schools.com/colors/colors_names.asp - Hex values can also be used. These color names and hex values are used for 1C-5C.

Bold: \<b\>...\</b\> but bold for 1M and 1R may cause misalignment. Use a color instead.

Italic: \<i\>...\</i\> but bold for 1M and 1R may cause misalignment. Use a color instead.
