dimension-comparison-pairwise {crunch} | R Documentation |
Given a single baseline column compare each other row or column against this
baseline. Internally this function uses compareDims()
iteratively.
compareColsPairwise(cube, ...)

baseline |
a character, the column to use as a baseline to compare against all other columns |
Warning since there is more than one comparison being made against each
baseline the z-scores, and especially the p-values derived from these
z-scores should be interpreted with caution. Using standard p-value cutoffs
will result in anti-conservative interpretations because of the
multiple
comparisons problem.
Adjustments to p-value cut offs (e.g.
Bonferonni correction)
should be used when interpreting z-scores from the
compare[Rows|Cols|Dims]Pairwise()
family of functions.
an array of z-score for the all the columns or rows compared to
