Select features based on variance threshold

Find out about the variance of each feature and filter out the ones below a certain threshold

variance_thresholding(data, threshold = 0)

Arguments

data	tibble. The features to select from
threshold	double. The variance threshold

Value

vector. The indexes of selected features

Examples

data <- data.frame(x1=c(1,2,3,4,5), x2=c(0,0,0,0,0), x3=c(1,1,1,1,1))
variance_thresholding(data)
#> [1] 1
