Forms a model formula using a set of structures supplied in a pointer.
Option
METHOD = string token |
Relationship of the structures within the formula (combined, crossed, nested); default comb |
|---|
Parameters
POINTER = pointers |
Sets of structures to be used to form the formulae |
|---|---|
FORMULA = formula structures |
Formulae constructed from the sets |
Description
SET2FORMULA forms a model formula using the contents (factors and/or variates) of a pointer. The pointer is specified by the POINTER parameter, and the formula is saved by the FORMULA parameter.
The METHOD option defines how the formula is constructed. With the combined setting, the formula has a single model term combining all the structures: for example
SET2FORMULA !p(A,B,C); FORMULA=Fcomb
sets up Fcomb as the formula
A.B.C
The crossed setting links the contents of the pointer using the operator *, so it would form the formula
A*B*C
The nested setting uses the operator /, so it would form
A/B/C
Option: METHOD.
Parameters: POINTER, FORMULA.
