Syntax MAPEi(X, Y, Ret_type) X is the original (eventual outcomes) time series sample data (a one dimensional array of cells (e.g. rows or columns)). Y is the forecast time series data https://www.youtube.com/watch?v=FPskDy9-GeE (a one dimensional array of cells (e.g. rows or columns)). Ret_type is a switch to select the return output (1=MAPE (default), 2=Symmetric MAPE (SMAPI)). Order Description 1 MAPE (default) 2 SMAPE Remarks MAPE is also referred to as MAPD. The time series is homogeneous or equally spaced. For a plain MAPE calculation, in the event that an observation value (i.e. ) is equal to zero, the MAPE function skips that http://www.spiderfinancial.com/support/documentation/numxl/reference-manual/descriptive-stats/mape data point. The mean absolute percentage error (MAPE), also known as mean absolute percentage deviation (MAPD), measures the accuracy of a method for constructing fitted time series values in statistics. The two time series must be identical in size. The mean absolute percentage error (MAPE) is defined as follows:
Where: is the actual observations time series is the estimated or forecasted time series is the number of non-missing data points When calculating the average MAPE for a number of time series, you may encounter a problem: a few of the series that have a very high MAPE might distort a comparison between the average MAPE of a time series fitted with one method compared to the average MAPE when using another method. In order to avoid this problem, other measures have been defined, for example the SMAPE (symmetrical MAPE), weighted absolute percentage error (WAPE), real aggregated percentage error, and relative measure of accuracy (ROMA). The symmetrical mean absolute percentage error (SMAPE) is defined as follows: The SMAPE is easier to work with than MAPE, as it has a lower bound of 0% and an upper bound of 200%. The SMAPE does not treat over-forecast and under-forecast equally. For a SMAPE calculation, in the event the sum of the obsForums Excel Questions Function to calculate MAPE Results 1 to 3 of 3 Function to calculate MAPEThis is a discussion on Function to calculate MAPE within the Excel Questions forums, part of http://www.mrexcel.com/forum/excel-questions/20193-function-calculate-mape.html the Question Forums category; Hi there, I'm trying to write a function in excel which will calculate the mean absolute percentage error (MAPE) for ...

Basically this is a measure of forecast accuracy, which compares forecasts for a variable against actual values. For those not familiar with this measure, basically I need a function that will calculate the absolute percentage difference between the values error in excel for two variables and return the average or sum of these: For example say we have two variables (X and Y) with following values: X Y The pct difference = 7 7 0 10 11 10 15 21 40 Average = 16.6 MAPE = 16.6 I know how to do these calculations within a spreadsheet but I want to do using a custom function. Also I know how to create inputboxes for the user to select the ranges for X and Y but I just haven't got a clue how to write the actual basic formula to calculate differences in values between two arrays and calculate statistics on these. I hope someone out there can help me.
