identify_outlier: Identify metric outliers over a date interval

Description

This function takes in a selected metric and uses z-score (number of standard deviations) to identify outliers across time. There are applications in this for identifying weeks with abnormally low collaboration activity, e.g. holidays. Time as a grouping variable can be overridden with the group_var argument.

Usage

identify_outlier(data, group_var = "Date", metric = "Collaboration_hours")

Value

Returns a data frame with Date (if grouping variable is not set), the metric, and the corresponding z-score.

Arguments

data

A Standard Person Query dataset in the form of a data frame.

group_var

A string with the name of the grouping variable. Defaults to Date.

metric

Character string containing the name of the metric, e.g. "Collaboration_hours"
