taba: Robust Correlation

In Taba: Taba Robust Correlations

Description

Returns the Taba robust linear, Taba rank (monotonic), TabWil, or TabWil rank correlation coefficient between two numeric vectors.

Usage

taba(x, y, method = c("taba", "tabarank","tabwil", "tabwilrank"), omega)

Arguments

x	A numeric vector of length greater than 2 must be same length as y
y	A numeric vector of length greater than 2 must be same length as x
method	A character string of "taba", "tabarank", "tabwil", or "tabwilrank" determining if one wants to calculate Taba linear, Taba rank (monotonic), TabWil, or TabWil rank correlation, respectively. If no method is specified, the function will output Taba Linear correlation.
omega	Numeric allowing the user to alter the tuning constant. If one is not specified, the function will default to 0.45 for Taba and Taba rank, and 0.1 for TabWil and TabWil rank. Range is between 0 and 1.

Details

This function can be used to compare two non-empty numeric vectors of length greater than two, or two columns of a data frame or matrix composed of more than two numeric elements. Missing values in either x or y are deleted row-wise. The default method is Taba Linear correlation, with the tuning constant omega.

Value

This function returns a the robust linear or monotonic association between two numeric vectors as a numeric.
