Potentiostatic, galvanostatic and cyclic potentiodynamic depositions of polyaniline were studied by cyclic voltammetry and in-situ Raman spectroscopy. Multivariate analysis of the spectroelectrochemical data including evolving factor analysis, multivariate curve resolution and 2Dcorrelation spectroscopy was applied to resolve overlapped bands in Raman spectra and to assign them reliably. Oxidiz...

Problems of regression smoothing and curve fitting are addressed via predictive inference in a flexible class of mixture models. Multidimensional density estimation using Dirichlet mixture models provides the theoretical basis for semi-parametric regression methods in which fitted regression functions may be deduced as means of conditional predictive distributions. These Bayesian regression fun...

We present self-modeling regression models for flexible nonparametric modeling of multiple outcomes measured longitudinally. Based on penalized regression splines, the models borrow strength across multiple outcomes by specifying a global time profile, thereby yielding a means of dimension reduction and estimates of trend more precise than those based on univariate regressions. The proposed mod...
