%description
Calculations of the most common metrics of automated advertisement and
plotting of them with trend and forecast. Calculations and description of
metrics is taken from different RTB platforms support documentation.
Plotting and forecasting is based on packages 'forecast', described in Rob
J Hyndman and George Athanasopoulos (2021) "Forecasting: Principles and
Practice" <https://otexts.com/fpp3/> and Rob J Hyndman et al
"Documentation for 'forecast'" (2003)
<https://pkg.robjhyndman.com/forecast/>, and 'ggplot2', described in
Hadley Wickham et al "Documentation for 'ggplot2'" (2015)
<https://ggplot2.tidyverse.org/>, and Hadley Wickham, Danielle Navarro,
and Thomas Lin Pedersen (2015) "ggplot2: Elegant Graphics for Data
Analysis" <https://ggplot2-book.org/>.
