Exploring the river nitrate data
In this exercise, you'll explore the river
dataset which will be used throughout this chapter to illustrate the use of common anomaly detection techniques. The river
data is a data.frame
that contains the following three columns:
index
- integers describing the order of thenitrate
observationsnitrate
- monthly concentrations of dissolved nitrate found in a rivermonth
- a factor containing the month for eachnitrate
observation
You will explore the nitrate
column using summary statistics and boxplots to assess whether there may be point anomalies present.
