There is nothing better than good old statistics in the era of ml/nn

Good discussion - especially of why you chose to use Poisson.

Excellent explanation and well presented, appreciated!
Would be nice to make a video about using formula in smoothing function in ggplot2, e.g. sometimes square term is used as a predictor in poisson regression and then just glm method in smoothing function will not be sufficient.

At the very end of the video I think you were hinting to a zero inflated model to account for the zeros...

Andrew, Your point about the missings is interesting but it only amounts to a percent (113 hrs) and may thus not be worth trying to impute. Besides that there could be simple explaination for the missing hours. Perhaps the bike company was closed for a holiday and/or buisness-related activities. Imputation might therefore not be warranted.

There is only ONE value with heavy rain/ snow so why not just skip it??? (run Bikeshare |> count(weathersit) for a table).
