Diagnostics information: Column proportions test

When you run a statistical test on a table, UNICOM Intelligence Professional can create diagnostics information that shows the p values and some of the intermediate figures used to calculate the statistics. The information is in comma-delimited format, so you can open it in Microsoft Excel and perform calculations on the data. The information varies according to the test. Here is the information for the first column proportions test example (see Examples of the column proportions test)

Tstats for table 'Table2' layer 1: overlap not specified: unweighted: effective base used

row/cols

This is in the form nxy, where n represents the category row (the first category row is 1, the second category row is 2, etc.) and x and y are the IDs of the pair of columns.

pval

The p value.

tval

The t value.

dof

The degrees of freedom.

se

The standard error.

sig

The significance level chosen for the test.

p1, p2

The proportions in the two columns.

r1, r2

The counts in the two cells. If the table is weighted, these are weighted.

w1, w2

The bases in the two columns. If the table is weighted, these are weighted.

e1, e2

The effective base in the two columns. These are the same as the bases if the effective base option was not used.
