Computation of the Average Run Length (ARL) for a Weighted Chi-Squared control chart for a given mean vector, delta, correlation matrix, R, control limit, h, and the vector of weights, w. The mean vector, delta, is defined in Propositon 4.2 from Paper Criticality Assessment for Enhanced Multivariate Process Monitoring.
