Multivariate image analysis methods applied to XPS imaging data sets

Recent improvements in imaging photoelectron spectroscopy enhance lateral and vertical characterization of heterogeneous samples at the cost of increasing complexity in the XPS data sets acquired. These imaging data sets require more sophisticated analysis methods than visual inspection if the data are to be interpreted effectively. Multivariate analysis (MVA) methods are increasingly utilized ...

Applied Multivariate Statistics for Ecological Data ECO632

The purpose of this lab exercise is to get to know your data set and, in particular, screen for irregularities (e.g., outliers) and transform and/or standardize data if appropriate. Data screening is an essential precursor to all statistical analyses and data transformations and standardizations are commonly applied prior to many techniques. Note, all data sets are unique and thus the procedure...

Multivariate Analysis Applied in Bayesian Metareasoning

As Bayesian networks are applied to more complex and realistic real-world applications, the development of more efficient inference approaches is increasingly important. This paper presents a method for metareasoning in Bayesian networks adopting prediction models to select algorithms for the inference tasks, when multiple schemes are used to calculate the propagation of evidence. The proposed ...
