What are ‘percentages’ and ‘statistics’?
When suppressing percentages with small bases, the word percentage means any of the following:
op=& | Total percentages |
op=0 | Row percentages |
op=2 | Column percentages |
op=5 | Column percentages printed for base row |
op=6 | Column percentages on most recent as well as first base |
op=8 | Indices |
op=A | Percentage differences (last element minus current element) |
op=B | Percentage differences (this element minus last element) |
Tables that are specified without any of these output types, either explicitly with op= on the tab statement or implicitly from an op= carried over from a higher level, are not subject to small percentage suppression even if the run requests it. (This allows you to specify smbase on the a statement but prevents Quantum from manipulating the output options for tables, such as those with absolutes only, where small percentage suppression is inappropriate.)
The word statistics refers to:
n12 | Mean |
n17 | Standard deviation |
n19 | Standard error |
n20 | Sample (error) variance |
All other statistics are always left untouched regardless of the size of the base.
