Coefficient matrices {Rfast}

Coefficient matrices.

Description

Coefficient matrices.

Usage

coeff(x, method,vector = FALSE)

Arguments

x

A matrix with data. The distances will be calculated between pairs of rows. In the case of vecdist this is a vector. For the haversine distance it must be a matrix with two columns, the first column is the latitude and the second the longitude.

method

See details for the available methods.

vector

For return a vector instead a matrix.

Details

• bhattacharyya : \sum \sqrt(P_i * Q_i)

Value

A square matrix with the pairwise coefficients.
