The matrix data file includes two special variables
created by the program: ROWTYPE_ and VARNAME_.
ROWTYPE_ is a
short string variable with values MEAN, STDDEV, and N.
VARNAME_ is a
short string variable that never has values for procedure ONEWAY. VARNAME_ is included with the matrix materials so that matrices written by ONEWAY can be read by procedures that expect
to read a VARNAME_ variable.
The independent variable is between variables ROWTYPE_ and VARNAME_.
The remaining variables in the matrix file are the
dependent variables.
