ATR-FTIR (Attenuated Total Reflectance Fourier Transform Infrared) spectra of prehardened epoxies with varying amounts of hardener and resin (mix ratio) have been acquired on a Midac FTIR spectrometer. The spectra form a set of training spectra for partial least-squares (PLS) analysis which was then used to analyze a series of epoxies of unknown mix ratio. The PLS model predicted the unknown mi...

We present an extension of PLS—called partial least squares correspondence analysis (PLSCA)—tailored for the analysis of nominal data. As the name indicates, PLSCA combines features of PLS (analyzing the information common to two tables) and correspondence analysis (CA, analyzing nominal data). We also present inferential techniques for PLSCA such as bootstrap, permutation, and χ2 omnibus tests...

This chapter introduces a novel Levenberg-Marquardt like second-order algorithm for tuning the Parzen window σ in a Radial Basis Function (Gaussian) kernel. In this case, each attribute has its own sigma parameter associated with it. The values of the optimized σ are then used as a gauge for variable selection. In this study, the Kernel Partial Least Squares (K-PLS) model is applied to several ...

Voluminous studies use Partial Least Squares Structural Equation Modeling (PLS-SEM) to analyze data. One of the reasons for using PLS-SEM is when structural model complex. Studies employing complex models with many constructs and indicators lead selection analysis. The purposes assessing measurement are examine basic dimensions construct variables, validate dimensions, determine number each con...

 The complex information systems such as enterprise resource planning (ERP) systems are essential for organizations to make them competitive. However, the success of ERP system projects is a difficult process as it involves different types of end user assessment. The main objective of the present study is to find the key determinants that open the door to employee satisfaction and adoption of E...
