The problem with parallel analysis for categorical variables is due to using poly choric correlations.

One obvious candidate is that the two 100 Ω Ω resistors are in parallel with each other. Two resistors of equal value in parallel are equivalent to half the resistance, or 50 Ω Ω in this case. The other candidate is the 40 Ω Ω, 200 Ω Ω pair. These are in series. The equivalent resistance of the pair is the series combination, or 240 Ω Ω.Numerical Example.
