OneVar

OneVar [1,]X[,[Freq][,Category,Include]]

OneVar [n,]X1,X2[X3[,…[,X20]]]

Calculates 1-variable statistics on up to 20

lists. A summary of results is stored in the

stat.results variable. (See page 172.)

All the lists must have equal dimension

except for Include.

Freq is an optional list of frequency values.

Each element in Freq specifies the

frequency of occurrence for each

corresponding X and Y data point. The

default value is 1. All elements must be

integers ≥ 0.

Category is a list of numeric category codes

for the corresponding X values.

Include is a list of one or more of the

category codes. Only those data items

whose category code is included in this list

are included in the calculation.

An empty (void) element in any of the lists

X, Freq, or Category results in a void for

the corresponding element of all those lists.

An empty element in any of the lists X1

through X20 results in a void for the

corresponding element of all those lists. For

more information on empty elements, see

page 232.
