PLOT Subcommand (ALSCAL command)

PLOT controls the display of plots. The minimum specification is simply PLOT to produce the defaults.

DEFAULT. Default plots. Default plots include plots of stimulus coordinates, matrix weights (if the model is INDSCAL, AINDS, or GEMSCAL), and stimulus weights (if the model is AINDS or ASCAL). The default also includes a scatterplot of the linear fit between the data and the model and, for certain types of data, scatterplots of the nonlinear fit and the data transformation.

ALL. Transformation plots in addition to the default plots. A separate plot is produced for each subject if CONDITION=MATRIX and a separate plot for each row if CONDITION=ROW. For interval and ratio data, PLOT=ALL has the same effect as PLOT=DEFAULT. This option can generate voluminous output, particularly when CONDITION=ROW.

Example

ALSCAL VAR=V1 TO V8 /INPUT=ROWS(8) /PLOT=ALL.

• This command produces all of the default plots. It also produces a separate plot for each subject’s data transformation and a plot of V1 through V8 in a two-dimensional space for each subject.
