covsim: An R Package for Simulating Non-normal Data for Structural Equation Models Using Copulas
Grønneberg, Steffen; Foldnes, Njål; Marcoulides, Katerina (Peer reviewed; Journal article, 2022)In factor analysis and structural equation modeling non-normal data simulation is traditionally performed by specifying univariate skewness and kurtosis together with the target covariance matrix. However, this leaves ... -
Non-normal Data Simulation using Piecewise Linear Transforms
Foldnes, Njål; Grønneberg, Steffen (Peer reviewed; Journal article, 2021)We present PLSIM, a new method for generating nonnormal data with a pre-specified covariance matrix that is based on coordinate-wise piecewise linear transformations of standard normal variables. In our presentation, the ...
