Taba (version 0.1.0)

taba: Robust Correlation

Description

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

Usage

taba(x, y, method = c("taba", "tabarank"), omega = 0.45)

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" or "tabarank" determining if one wants to calculate Taba linear or Taba rank (monotonic) 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. Range is between 0 and 1.

Value

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

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 equal to 0.45.
