Function outliers

ArrayUtils

Find outliers in an array of numbers.

An outlier is an observation that lies an abnormal distance from other values in a dataset. This function calculates the average and standard deviation of the array, and then finds the values that are beyond the threshold (threshold = average + 2 * standard deviation).

Example

const data = [10, 15, 12, 14, 8, 100, 9];
const outliers = findOutliers(data);
console.log(outliers); // Output: [100]
