| clquar | Computing quartiles for classes |
| -c <cldata> | classified data for defining classes |
| -d <srcdata> | source data |
| -dout <trgdata> | target data for statistics in classes |
| [-v <portion>] | the perceptual portion of the data (default 50%) |
| [-ext <extension>] | the extension for variables |
| [-md <value>] | missing value to be skipped |
This operation finds values in fields so that the given portion of the data will be left within the values. The procedure is performed for each field separately and results are stored with the names of the fields specified with an extension.
| cladev | Computing deviations |
| -c <cldata> | classified data for defining classes |
| -d <srcdata> | source data |
| -dout <trgdata> | target data for statistics in classes |
| -ext1 <ext1> | the extension for the variable avg-dev |
| -ext2 <ext2> | the extension for the variable avg+dev |
| [-md <value>] | missing value to be skipped |
The operation computes the values average 
deviation which will be stored with the extensions _ext1 and _ext2.
