Statistical package for factorial experiments (SPFE) 1.0 (Pamphlet)

Abstract

It generates the designs for symmetrical and asymmetrical factorial experiments with and without confounding. It also generates the randomized layout of the designs for factorial experiments. The design is generated on listing the independent interactions to be confounded. It also generates fractional factorial plans for symmetrical factorial experiments. The data generated through these designs are analyzed as per usual procedure of designs for single factor experiments. Contrast analysis is carried out to obtain the sum of squares of main effects and interactions. A null hypothesis on any other contrast of interest can also be tested. This package, besides being useful for the experimenters in the NARS, will be quite useful for teaching of Design and Analysis of Factorial Experiments in the classroom.
