The CHull procedure for selecting among multilevel component solutions
Chemometrics and Intelligent Laboratory Systems, 2011 Recently, Timmerman [1] proposed a class of multilevel component models for the analysis of two-level multivariate data. These models consist of a separate component model for each level in the data. Specifically, the between-differences are captured by a between-component model and the within-differences by a within-component model.

A Sizing Procedure for the DC-Side Capacitor of a Three-Phase Modular Multilevel Converter
Energies, 2023 The integration of photovoltaic (PV) modules with a modular multilevel converter (MMC) is very interesting because it allows us to exploit the intrinsic advantages of that converter, such as modularity and high voltage quality, and to implement ...

Comparison of Estimation Procedures for Multilevel AR(1) Models [PDF]
Frontiers in Psychology, 2016 To estimate a time series model for multiple individuals, a multilevel model may be used. In this paper we compare two estimation methods for the autocorrelation in Multilevel AR(1) models, namely Maximum Likelihood Estimation (MLE) and Bayesian Markov Chain Monte Carlo.
