T%CONTROL allows you to express the body of a table as percentages of the values of “control” levels of one or more of its classifying factors. These controls might be standard or check varieties in a variety trial, or placebo treatments in a medical trial, or zero levels of fertilizers in an agricultural field experiment, etc.
You supply the table using the
OLDTABLE parameter. You can save a new table containing the percentages using the
NEWTABLE parameter. The factors containing the control levels are specified by the
FACTOR parameter; if there are several you must put them into a pointer.
FACTOR need not be set if the tables are one-way. The
CONTROL parameter identifies the control levels of each factor. Usually the factor will have a single control, specified either by giving its level (in a scalar) or its label (in a string or single-valued text). Alternatively, you can define several controls, by specifying a variate (of levels) or a multi-valued text (of labels);
T%CONTROL then takes means over the control levels. Again, if there are several factors, you must put the corresponding
CONTROL settings into a pointer. If
CONTROL is unset or missing for any factor,
T%CONTROL uses its reference level.
Not all the factors in the table need to have control levels. Suppose, for example, we have a 2-way table with factors
B where the first level of
A (a1) is the control. Then the cell (ai, bj) will be given as a percentage of the cell (a1, bj).
T%CONTROL prints the table of percentages, but you can set option
PRINT=* to suppress this.
