dr.M: ~~function to do ... ~~

Description

Compute the kernel matrix for a dr method

Usage

dr.M(object, ...)

Arguments

object

An object of type 'dr'.

...

Additional method-specific arguments; see description below

Value

• Returns a list with components
• M
  The kernel matrix
• slice.info
  Information about the slices, if used by the dr method.
• ...

Details

This is a method-specific function to compute the kernel matrix M of a dimension reduction method. For sir, save, msir and save, the additional arguements are 'nslices', the number of slices to be used, and 'slice.info', which if present is the a list produced by dr.slices. For ols and the phd methods, no additional arguments are required. New dimension reduction methods can be added to 'dr' by writing a new 'dr.M' method.
