However, the collection of accurate income and consumption data requires extensive resources for household surveys. Given the increasingly routine application of principal components analysis (PCA) using asset data in creating socio-economic status (SES) indices, we review how PCA-bas...

Alternatives to principal components analysis to derive asset-based indices to measure socio-economic position in low- and middle-income countries: the case for multiple correspondence analysis.

that the direct effects of the decrease in research funds will be more evident in the subsequent years.

Binary data comparison using similarity indices and principal components analysis

This work is a study of binary data, especially binary images sources of information widely used. In general, comparing two binary images that represent the same content is not always easy because an image can undergo transformations like: Translation, rotation, affinity, resolution change and scale or change in appearance. In this paper, we will try to solve the translation and rotation proble...
