More specifically, the lagged effect of credit sales and cash inflows is distributed over a number of periods in this way:
By using the regression method discussed in Chapter 16, we will be able to estimate these collection rates. We can utilize Regression of Excel or special regression packages such as SAS, Minitab and SPSS.
It should be noted that the cash collection percentages, (b1, b2, ... bi) may not add up to 100 percent because of the possibility of bad debts. Once we estimate these percentages by using the regression method, we should be able to compute the bad debt percentage with no difficulty.
