Plots selected direction vectors determined by a dimension reduction regression fit. By default, the pairs function is used for plotting, but the user can use any other graphics command that is appropriate.
dr.directions
(Package: dr) :
Directions selected by dimension reduction regressiosn
Dimension reduction regression returns a set of up to p orthogonal direction vectors each of length p, the first d of which are estimates a basis of a d dimensional central subspace. The function returns the estimated directions in the original n dimensional space for plotting.
dr
(Package: dr) :
Main function for dimension reduction regression
This is the main function in the dr package. It creates objects of class dr to estimate the central (mean) subspace and perform tests concerning its dimension. Several helper functions that require a dr object can then be applied to the output from this function.
dr.weights
(Package: dr) :
Estimate weights for elliptical symmetry
This function estimate weights to apply to the rows of a data matrix to make the resulting weighted matrix as close to elliptically symmetric as possible.
