pop_dextract

extracts the matrix of detrimental information with one of these methods: IIR ('iirp'), EPO ('epo'), EROS('eros' ou 'epoe')

Calling sequence

dmatrix = pop_dextract(method,x_ed,(classes_indiv),(classes_perturb))

Arguments

x_ed:

a matrix (n1 x q) from an experimental design or a Div structure

(classes_indiv):

a vector identifying the individuals of x_ed (for 'epo','eros' or 'epoe')

(classes_perturb):

a vector identifiant the level of detrimental influence for each observation of xg ( for 'epo')

dmatrix:

a matrix containing only detrimental information

the dimensions of dmatrix.d depend on the chosen method

Examples

[dmatrix]=pop_dextract('eros',xg,cl_ech)
[dmatrix]=pop_dextract('epo',xg,cl_ech,cl_pert)
