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.

Notes

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


Example

Example 1

Statistics are calculated for the field Au.

!STATNP     &IN(ASSAYS), F1(Au)

Example 2

Statistics are calculated for all numeric fields in the file.

!STATNP     &IN(ASSAYS)

 


Error and Warning Messages

Message

Description

Solution

>>> 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.
