Get the mean applying some weights
Usage
weighted_mean(y, weights = NULL, norm = TRUE)
Arguments
- y
a vector to compute the mean for
- weights
the vector of weights, can be NULL, then will just return mean
- norm
normalize the weights so that they have mean of 1, default is
to normalize
Examples
y <- rnorm(100)
w <- runif(100)
weighted_mean(y, weights = w)
#> [1] 0.1045551
