An important circuit-analysis technique involves replacing resistors connected in parallel with one resistor whose value is equal to the equivalent resistance. If your calculations produce an equivalent resistance that is larger than (or equal to) any resistor in the network, something went wrong, because even the smallest resistor in a ...Specifically, parallel analysis (factoring null matrices based on 10,000 observations and 20 variables) generated mean values λ1 and λ2 values of 1.08 and 1.06 with 20 variables. The obtained λ1 is clearly larger and the obtained λ2, is clearly smaller than these values with all degrees of categorization.3: Parallel RLC Circuits.

We suggest that factor analysis is preferable to principal components analysis. Components analysis is only a data reduction method. It became common decades ago when computers were slow and expensive to use; it was a quicker, cheaper alternative to factor analysis (Gorsuch, 1990). It is computed without regard to any underlying structure caused by3.4: Parallel Circuit Analysis. Kirchhoff's current law (KCL) is the operative rule for parallel circuits. It states that the sum of all currents entering and exiting a node must equal zero. Alternately, it can be stated as the sum of currents entering a node must equal the sum of currents exiting that node.Parallel analysis (Horn, 1965) helps to make the interpretation of scree plots more objective.The eigenvalues of R xx are plotted with eigenvalues of the reduced correlation matrix for simulated variables with population correlations of 0 (i.e., no common factors).
