A time series is a set of data points collected at regular intervals of time. Sometimes, the data points in a time series change over time in a predictable way. This is called a stationary time series. Other times, the data points change in an unpredictable way. This is called a non-stationary time series.

In my post I make use of #lapply and #map_if from #purrr out of the #tidyverse

There might be times when you may want to get some sort of #summary #statistic like a #quantile or #IRQ on your #distribution data.
With my #r #package {TidyDensity} this is possible given the data comes from a tidy_ distribution function. If you have a vector of data you can use tidy_empirical() as a cheat.
With this function you can get output as #sapply #lapply #tibble or a #tibble where #datatable is doing the work.
