Exercise

90 and 95% bands

You are looking at a 40-day rolling average of the NO2 pollution levels for the city of Cincinnati in 2013. To provide as detailed a picture of the uncertainty in the trend you want to look at both the 90 and 99% intervals around this rolling estimate.

To do this, set up your two interval sizes and an orange ordinal color palette. Additionally, to enable precise readings of the bands, make them semi-transparent, so the Seaborn background grids show through.

Instructions

  • Set the opacity of the intervals to 40%.
  • Calculate the lower and upper confidence bounds.
