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 = "MetricDate",
metric = "Collaboration_hours"
)

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