diffMeans | R Documentation |
Calculates the difference of mean observed outcomes for a specified treatment factor and specified pair of comparison levels.
diffMeans(y, w, calcOptions = NULL)
y |
a vector or matrix of outcomes. |
w |
a vector or matrix of assignments. |
calcOptions |
a list of options for calculating the difference of mean outcomes (if necessary).
|
The difference of mean observed outcomes.
