STATNP Process

To access this process:

Sample Analysis ribbon >> Statistics >> Statistics Processes >> Nonparametric Statistics.
View the Find Command screen, select STATNP and click Run.
Enter "STATNP" into the Command Line and press <ENTER>.

See this process in the Command Table.

Process Overview

Calculates non-parametric summary statistics on numeric fields in a file.

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.

Note: By default, statistics are calculated for all numeric variables (up to 10 fields can be defined; more than 10 if a &FIELDLST is specified).

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 a file.

Error and Warning Messages

Message	Description
>>> ERR 121 <<< ( fileno) IN STATNP	File read error. Fatal; the process is exited. Check the &IN file and its fields.
>>> ERR 122 <<< ( fileno) IN STATNP	No numeric fields in file, or fields specified were not numeric. Fatal; the process is exited. Check that the &IN file contains numeric fields.
DATA FILE EMPTY - PROCESS TERMINATED	The input file contains no data. Fatal; the process is exited. Check that the &IN file contains data.
