Case-Mix Adjustment of Adherence Based Pharmacy Quality Indicator Scores
… performance of a classical logistic regression model containing only patient characteristics and a random-effect model including patient characteristics and a pharmacy-specific effect in predicting medication adherence. These models were used to compute three different risk-adjusted scores on …

How Industry Concentration Influences the Performance of South African General Equity Funds
… Over the period from 2006 to 2017, a mixed model regression, which accounts for both fixed and random effects, is used to determine the impact of concentration on fund performance. A random effect model was used as it models the variability between funds. The fixed effects that were …

On the multivariate components of variance problem
… on the variance components in univariate mixed effect models have been developed and extensively used in many fields. Development for multivariate mixed models has been relatively limited. One important issue in the multivariate problem is determining the rank of a covariance component. Testing …
