Principal Components Analysis , Exploratory Factor Analysis , and Confirmatory Factor Analysis
Principal components analysis and factor analysis are common methods used to analyze groups of variables for the purpose of reducing them into subsets represented by latent constructs (Bartholomew, 1984; Grimm & Yarnold, 1995). Even though PCA shares some important characteristics with factor analytic methods such as exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), the ...
متن کاملSkew Detection via Principal Components Analysis
Skew detection via principal components is proposed as an e ective method for images which contain other parts than text It is shown that the negative of the image leads to much more robust results and that the computation time involved is still practical This method is also shown to be e ective for single word skew detection
متن کاملInfinite Sparse Factor Analysis and Infinite Independent Components Analysis
A nonparametric Bayesian extension of Independent Components Analysis (ICA) is proposed where observed data Y is modelled as a linear superposition, G, of a potentially infinite number of hidden sources, X. Whether a given source is active for a specific data point is specified by an infinite binary matrix, Z. The resulting sparse representation allows increased data reduction compared to stand...
متن کاملBayesian Factor Analysis via Concentration
We consider factor analysis when we assume the distribution form is known up to its mean and variance. A prior is placed on the mean and variance and then inference is made as to whether or not any latent factors exist. Inference is carried out by comparing the concentrations of the prior and posterior about various subsets of the parameter space that are specified by hypothesizing factor struc...
متن کاملFactor Analysis of Seed Yield, Its Components and Oil Content of Corn Genotypes Affected Nitroxin Fertilizer
Fertilizer management is essential for achieving sustainable agriculture and protecting the environment. To evaluate the effect of Nitroxin bio-fertilizer application on quantitative and qualitative traits of corn hybrids a farm research was arranged via split plot experiment based on the randomized complete block design with four replications in 2013. Main plots were Included: use of the chemi...
