Diagnostics information: Net difference 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 Example of the net difference test:
row/cols
This is in the form n/(3-4)-(1-2), where n represents the category row (the first category row is 1, the second category row is 2, etc.) and 1, 2, 3, and 4 are the IDs of the four 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.
eb
The effective base for the column.
p1, p2, p3, p4
The proportion in columns 1, 2, 3, and 4.
r1, r2, r3, r4
The counts in columns 1, 2, 3, and 4.
w1, w2, w3, w4
The sum of weights (weighted base) for columns 1, 2, 3, and 4.
e1, e2, e3, e4
The effective base in columns 1, 2, 3, and 4.
