Compute outlier flags.

Source: R/filter.R
identify_vector_outliers_global.Rd

The outlier detection method is based on quantiles but permits retaining short tails. A sample is considered an outlier if it is outside an interval computed as (lo - range * slack, hi + range * slack) with lo and hi denoting the limit and 1 - limit quantiles and range = hi - lo.

Usage

identify_vector_outliers_global(.input, .limit = 0.05, .slack = 0.1)

Arguments

.input

Sample vector.

.limit

Quantile that separates inliers from outliers.

.slack

Tolerated distance from limit quantile.

Value

Boolean vector of outlier flags.
