✦ Synopsis

In thie paper we preaent a procedure to meewvB the degree of imbalance of an unbdanoed dab set. The procadnre ie baaed on chooeing an appropriate loglinear model for the mbclaaa fquenciea of the data. A meaeure of imbalsnce ie then introduced 88 nome function of the chi-squared etetistic need in the goodness-of-fit taet for the loglinear model. The propod p d u r e am ale0 be used fo measure departmw from certain tspea of balance, such aa proportionality of mbcleee frequencies, partial belence, end leet-stage nniformify.

Traditional system dynamics models are subject to error in the estimation of performance measures because of the method of calculation over discrete time intervals. It is shown that such errors may be signi®cantly reduced by dividing the computation between two runs with dierent solution intervals a

## Abstract This paper analyses the load‐harmonic modelling under unbalanced conditions. It presents a harmonic characterization of linear three‐phase loads (three‐phase P‐Q consumptions) for different impedance configurations and analytical models for an ideal six‐ and twelve‐pulse converter suppl

The general linear mixed model provides a useful approach for analysing a wide variety of data structures which practising statisticians often encounter. Two such data structures which can be problematic to analyse are unbalanced repeated measures data and longitudinal data. Owing to recent advances
