WebMean shift is an application-independent tool suitable for real data analysis. Does not assume any predefined shape on data clusters. It is capable of handling arbitrary feature spaces. The procedure relies on choice of a single parameter: bandwidth. The bandwidth/window size 'h' has a physical meaning, unlike k -means.

In common practice, factor scores are calculated with a mean or sum of measured variables that “load” on a factor. The EFA Model is Y = Xβ+ E where Y is a matrix of measured variables X is a matrix of common factors

WebIn statistics, confirmatory factor analysis ( CFA) is a special form of factor analysis, most commonly used in social science research. [1] It is used to test whether measures of a construct are consistent with a researcher's understanding of the nature of that construct (or factor). As such, the objective of confirmatory factor analysis is to ... Webanalysis of variance (ANOVA), for one factor of interest, and a generalization of the two-sample t-test. The two-sample t-test is used to decide whether two groups (levels) of a factor have the same mean.

"Factor analysis is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved variables called factors. For example, it is possible that variations in six observed variables mainly reflect the variations in two unobserved (underlying) variables. Factor analysis searches for such joint variations in response to unobserved latent variables. The observed variables are modelled as linear combinations of th… " - Mean factor analysis
