Introduction
Calculates non-parametric summary statistics on numeric fields in a file.
How to use
The following statistics are calculated for each numeric variable in turn:-
- total number of records in the file.
- number of samples (excluding absent data).
- number of absent data values.
- minimum, maximum and range.
- mid-range.
- median and median deviation.
- 10th and 90th percentile.
These results are displayed on the terminal, and can be copied to the print device. In addition a cumulative frequency plot on a normal probability scale can be calculated for each variable, and sent to the printer or printfile.
