A Solution To the Problem of "Differences in Units of Measure"

It has been suggested that researchers comparing causal models across populations employ path regression coefficients corrected for unreliability. This procedure, however, does not eliminate the problem of differences in the units of measure across populations. This paper outlines a technique designed to eliminate this problem by comparing "effect ratios," rather than effect coefficients, across populations. Both hypothetical and real data are used to demonstrate the technique.
