Abstract: Path analysis was first proposed by Wright (1934) as a means for analyzing the path coefficients within noncausal models. More recent texts concerned with regression models (Cohen & Cohen, 1983; Pedhazur, 1982) have devoted considerable space to the statistical methods used for the calculation of path coefficients within the path analytic framework. These regression methods provide the researcher with direct paths between variables, but in the absence of extended analysis, fail to provide information regarding the indirect paths, the unanalyzed effects, or the spurious effects among variables. Fox (1980; cited by Pedhazur, 1982) provided the means for computing indirect, spurious, and unanalyzed effects using a series of matrix manipulations. Pedhazur (1982) recommended the method for complex models; however, Fox (1980) presented the methods in APL (a programming language that is rarely implemented) and offered to send the FORTRAN listing to interested readers. Thus, this valuable method seems to be largely unavailable to those who need to calculate the more subtle effects for complex path analytic models.
