Parallel analysis is implemented for R in the paran package available on CRAN here. The basic logic behind parallel analysis is to improve upon the eigenvalue > 1 (principal component analysis) or eigenvalue > 0 (common factor analysis), by (1) recognizing that in finite data, some eigenvalues will be greater than 1 or less than 1 simply due ...Parallel thinking is a method of thinking that involves exploring a problem or opportunity from different angles at the same time, rather than sequentially or adversarially. It was developed by ...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.To determine the number of factors to be extracted, three different statistical methods were used: Kaiser’s rule (i.e., number of eigenvalues greater than 1, Kaiser 1960), scree test (Cattell, 1966) and parallel analysis (PA, Horn 1965).
