Abstract

Title: Erratum: Jamšek et al. Gaussian Mixture Models for Control of Quasi-Passive Spinal Exoskeletons. <i> Sensors </i> 2020, <i> 20 </i> , 2705 Authors: ['Marko Jamšek' 'Tadej Petrič' 'Jan Babič'] There was an error in the original article [1]. The variable used for the superscript in the denominator of the equation, denoting the dimensionality of the model, was incorrectly written as K and thus conflicted with the variable denoting the number of Gaussian mixtures. A correction has therefore been made to Section 2.3, Equation (4): <EQ id="FD1">**(4)**p_{j}(x)=\underset{k=1}{\overset{K}{\sum}}τ_{k}\frac{e-\frac{1}{2}(x-μ_{k})TΣ_{k}^{-1}(x-μ_{k}}{2π)D|Σ_{k}|},</EQ> where *D* is the dimensionality of the model (6 in our case).
