cspcana

principal component analysis on centered-standardized data

Calling sequence

model=cspcana(x)

Arguments

x:

a matrix (n x q) or a Div structure

model:

a structure containing the following fields:

model.scores: scores of the observations onto the eigenvectors

model.eigenvec: eigenvectors or loadings

model.var_scores: scores of the variables onto the eigenvectors

model.eigenval: eigenvalues

model.x_mean: mean vector of the columns of x

model.x_stdev: standard-deviations vector of the columns of x (calculated with (n-1))

model.centred: 1=x centred

model.std: 1=x standardized

Examples

[model]=cspcana(x)
