Possibility to enter stock data with sales and mark special days like Launnch day or Black Friday #9250

I have been looking for a way to also report my current stock or when sales are 0, mark them as special case where stock is also 0. When an item is out of stock, sales are 0, but that does not mean there is no demand.

There are days or months when sales are way out of average, this is especially true for launch day or even Black Friday. I would the option to mark such sales so they wouldn't influence future sales.

Hi @Vampirtc, it seems your issue seems unrelated to statsmodels. For simple data transformations and processing, you might find repo like pandas more suitable.

Hi, using SARIMAX, doesn't that fit?

If you want to build a model and predict for the future not just mark existing data, pandas like indeed not sufficient.
