Pearson-Filon Statistic

[Karl L. Wuensch]

Title: Re: [edstat] Testing differences between non-independent correlations

Raghunathan, Rosenthal, and Rubin (1996, Psychological Methods, 1, 178-183) demonstrated that a modified Pearson-Filon statistic, the ZPF statistic, is superior to the PF statistic.  See http://core.ecu.edu/psyc/wuenschk/StatHelp/ZPF.doc . ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Karl L.

See Jim Steiger's 1980 Psych.Bull paper. David Kenny's 1987 book also covers it, but there is a mistake in the formula on p.280: the denominator should have Q/(1-r^2)^2, not Q(1-r^2)^2.
