The functions available are the following:
TOT: show sum of each column in
Σ
DATA matrix.
MEAN: shows average of each column in
Σ
DATA matrix.
SDEV: shows standard deviation of each column in
Σ
DATA matrix.
MAX
Σ
: shows maximum value of each column in
Σ
DATA matrix.
MIN
Σ
: shows average of each column in
Σ
DATA matrix.
BINS: used as x
s
,
∆
x, n [BINS], provides frequency distribution for data in
Xcol column in
Σ
DATA matrix with the frequency bins defined as
[x

VAR: shows variance of each column in
Σ
DATA matrix.
PSDEV: shows population standard deviation (based on n rather than on (n-1))
of each column in
Σ
DATA matrix.
PVAR: shows population variance of each column in
Σ
DATA matrix.
MIN
Σ
: shows average of each column in
Σ
DATA matrix.
The PLOT sub-menu
The PLOT sub-menu contains functions that are used to produce plots with the
data in the
Σ
DATA matrix.
The functions included are:
BARPL: produces a bar plot with data in Xcol column of the
Σ
DATA matrix.
HISTP: produces histogram of the data in Xcol column in the
Σ
DATA matrix,
using the default width corresponding to 13 bins unless the bin size is
modified using function BINS in the 1VAR sub-menu (see above).
SCATR: produces a scatterplot of the data in Ycol column of the
Σ
DATA
matrix vs. the data in Xcol column of the
Σ
DATA matrix. Equation
fitted will be stored in the variable EQ.
