TOMS359
Factorial Analysis of Variance

TOMS359 is a FORTRAN77 library which implements ACM TOMS algorithm 359, for the factorial analysis of variance.

The text of many ACM TOMS algorithms is available online through ACM: http://www.acm.org/pubs/calgo or NETLIB: http://www.netlib.org/toms/index.html.

Usage:

call fnova ( y, z, row, msize, ncls, nfctr )

where
Y, the observed vector, of length NCLS,
Z, the output interaction vector of length NCLS,
ROW is a workspace vector whose length is (at least) the maximum of the entries in MSIZE,
MSIZE is a vector of size NFCTR, containing the factor sizes;
NCLS is the product of the factors;
NFCTR is the number of factors.

Languages:

TOMS359 is available in a FORTRAN77 version.
