elemfits: elemental fits

In Mufabo/Rrobustsp: Robust Signal Processing

elemental fits

Description

elemfits compute the Nx(N-1)/2 elemental fits, i.e., intercepts b_0,ij and slopes b_1,ij, that define a line y = b_0+b_1 x that passes through the data points (x_i,y_i) and (x_j,y_j), i<j, where i, j in 1, ..., N. and the respective weights | x_i - x_j |

Usage

elemfits(y, x)

Arguments

y	: (numeric) N vector of real-valued outputs (response vector)
x	: (numeric) N vector of inputs (feature vector)

Value

beta: (numeric) N*(N-1)/2 matrix of elemental fits

w: (numeric) N*(N-1)/2 matrix of weights
