Statistical package for factorial experiments (SPFE) 1.0

Abstract

The SPFE gives the designs for symmetrical and asymmetrical fctorial experiments and also performs analysis of the data generated. It generates randomized layout of the designs for factorial experiments with or without confounding. The software requires user input as a list of independent interaction to be confounded. Different interaction(s) can be assigned for confounding in different replications. It also generates regular fractional factorial plans for symmetrical factorial experiments. The data are analyzed as per procedure of blocked/unblocked designs for single factor experiments. The treatment sum of squares can be partitioned into sum of squares due to main effects and interactions. A null hypothesis on any constrast of interest can also be tested. The package is also useful for illustration puposes in the classroom teaching as well as for the researchers in Statistics with interest in experimental designs particularly in factorial experiments. The package has been developed using Microsoft Visual C++ 6.0, Microsoft Visual Basic 6.0 and Microsoft Access 2000.
