It is a pretty common technique that can be used in a lot of analysis scenario. If we have a factor column in an R data frame then it would not make sense to find the cumulative sum for all factor levels together, we must find the cumulative sums for each level. scenerios including pivot table, just like you would use Excel’s pivot table “show values as” and selecting “running total” or “% running total” SELECT item_id, sale_Date SUM(quantity * price) OVER(PARTITION BY item_id ORDER BY sale_Date ROWS BETWEEN UNBOUNDED PRECEDING) AS … A tensor of the cumulative sum of values of x along axis..
