PVAR
Type: Command
Description: Population Variance Command: Calculates the population variance of the coordinate values in
each of the m columns in the current statistics matrix (ΣDAT).
The population variance (equal to the square of the population standard deviation) is returned as a
vector of m real numbers, or as a single real number if m = 1. The population variances are
computed using this formula:
1
n
---
x
k
x–( )
2
k 1=
n
∑
where x
k
is the kth coordinate value in a column,
x
is the mean of the data in this column, and n is
the number of data points.

PVARS
Type: Command
Description: Port-Variables Command: Returns a list of the backup objects (:n
port
:name) and the library objects
(:n
port
:n
library
) in the specified port. Also returns the available memory size (RAM).
The port number, n
port
, must be in the range from 0 to 2.
