fact >> (X->X) Pretraitments by orthogonal projection > osc

osc

computes the parameters of orthogonal signal correction (OSC) according to the direct method

Calling sequence

[ploads,weights,tscores,evpcent]=osc(x_div,ndim);

Arguments

x_div:

a matrix (n x q) or a Div structure

ndim:

the number of dimensions

ploads:

the loadings or basis of the dropped space

ploads.d is a matrix of dimensions (q x ndim)

weights:

the weights

weights.d is a matrix of dimensions (q x ndim)

tscores:

the scores of the observations for the ndim dimensions

tscores.d is a matrix of dimensions (n x ndim)

evpcent:

the eigenvalues, in percent

evpcent.d is a vector of dimensions (ndim x 1)

Examples

[p,w,t,ev]=osc(x,5);
