 ## Libraries used
 
 In this session we will use the `nfidd` package to load a data set of infection times and access stan models and helper functions, the `dplyr`  and `tidyr` packages for data wrangling, `ggplot2` library for plotting, the `tidybayes` package for extracting results of the inference and the `scoringutils` package for evaluating forecasts.
-We will also use `qra` for quantile regression averaging in the weighted ensemble section.
