Weighted Average formula - beast mode
I am using a beast mode to calculate the weighted average of days between two dates (payment due date and invoice date). Formula here: SUM((`PAYMNT_DUE_DT`-`INVOICE_DT`)*`RECPT_AMT_USD`)/ SUM(`RECPT_AMT_USD`)
However, I realized there may be some zeros in the output that are possibly causing the weighted average to be skewed lower. Can someone let me know if there is something I should add to exclude zeros maybe?
