A recent study on the condition numbers of mixed least squares-total squares (MTLS) problem is due to Zheng and Yang (Numer Linear Algebra Appl. 2019;26(4):e2239). However, associated expressions are not compact Kronecker-product operations make computation costly. In this paper, we first present new alternative closed formula for order perturbation estimate MTLS solution. Then reveal relations...

Nonlinear structural equation modeling provides many advantages over analyses based on manifest variables only. Several approaches for the analysis of latent interaction effects have been developed within the last 15 years, including the partial least squares product indicator approach (PLS-PI), the constrained product indicator approach using the LISREL software (LISREL-PI), and the distributi...

Structural equation modelling (SEM) is now a popular technique in the social, behavioural and business sciences for exploring and assessing complex linear relationships among many variables, in particular between endogenous and exogenous latent variables that cannot be directly observed but that must be inferred by means of manifest indicator variables, that is variables measured without error....
