Accurate Closed-Form Approximations for the Sum of Correlated Weibull Random Variables

Abstract: In this letter, a highly accurate approximate approach for the sum of arbitrary correlated Weibull random variables is proposed. Specifically, closed-form approximate expressions for the ...

Why Ordinal Variables Can (Almost) Always Be Treated as Continuous Variables: Clarifying Assumptions of Robust Continuous and Ordinal Factor Analysis Estimation Methods

The analysis of factor structures is one of the most critical psychometric applications. Frequently, variables (i.e., items or indicators) resulting from questionnaires using ordinal items with 2–7 ...
