"WebIt is a variant of MAPE in which the mean absolute percent errors is treated as a weighted arithmetic mean. Most commonly the absolute percent errors are weighted by the actuals (e.g. in case of sales forecasting, errors are weighted by sales volume).. Effectively, this overcomes the 'infinite error' issue. Its formula is: " - Low percent error

WebUsually performance materiality is calculated at 50% to 75% of materiality. Why the range? Different risk levels for different clients. If you believe the risk of undetected misstatements is high, then use a lower percent (e.g., 55% of materiality). Likewise, if your client is not inclined to record detected errors, lower the percent. WebMPE is the mean percentage error (or deviation). It is a relative measure that essentially scales ME to be in percentage units instead of the variable’s units. The main advantage of MPE is that it lets you compare variances between differently scaled data. Formula
