Weighted bivariate correlation

Description

Computes the weighted Pearson correlation coefficient of two numeric vectors.

Usage

weighted.corr(x, y, w, na.rm = TRUE)

Arguments

x	(numeric vector) Variable of interest x for computing the correlation
y	(numeric vector) Variable of interest y for computing the correlation
w	(numeric vector) Vector with the weights
na.rm	(bool) if TRUE: Excludes missing values before computing the correlation

Value

Scalar containing the Pearson correlation coefficient

Examples

data(df_talis18) 

weighted.corr(x = df_talis18$t3stake, y = df_talis18$t3team, w = df_talis18$tchwgt)
