How to set up Excel to calculate the Mean Absolute Deviation (MAD) the Mean Square Error (MSE), The Root Mean Square Error (RMSE), and the Mean Absolute Percentage Error (MAPE). If you have zero or near zero actual values, you can use SMAPE instead of MAPE. You can download the latest version (August 2021) of the Excel worksheet here: www.drdawnwright.com/use-exce...

Thank you for explaining this all so easily. This video really helped me with these concepts I was struggling in. One note: My textbook says MAPE needs to be represented not by dividing by N, but by N minus 1, or 11 in the video's case. So if anyone is also struggling, that could by it.

Use SMAPE instead. ) values in the actual data distort MAPE. See the new version of the worksheet you can download www.drdawnwright.com/use-excel-to-calculate-mad-mse-rmse-mape/

Hi there, are there any ways to calculate QLike loss function on Excel? Thanks for your content. I achieved the same result for RMSE AND MSE with EViews.

@TheStatsFilesDawnWrightPhD 6 жыл бұрын

You can model QLike loss function in Excel, though I do not have a video on it now. The thrust of my work is on showing students how to do basic business analytics with just Excel and only the add-ins that come standard with Excel. EViews is nice but expensive.

Thank you for the video. I was taught that MSE is divided by n-1, as opposed to n. Is this correct?

@TheStatsFilesDawnWrightPhD 3 жыл бұрын

Most authors I know use n. I suspect there maybe some authors who use n-1. I used Evans' 5th Statistics, Data Analysis, and Decision Modeling. Here is a link to Wikipedia that also says use n. en.wikipedia.org/wiki/Mean_squared_error

hello, I am writing a paper on "state-dependent fiscal multiplier in Sub-Saharan Africa (SSA) countries" I want to identify fiscal identification shocks by a forecast error approach. Data: annual data from 15 SSA countries I read in one paper how to compute a forecast error of a variable. forecasts of government spending are taken from October publications of the IMF’s WEO. Then, the fiscal spending shocks are identified as the forecast errors of government spending. Thus, FEi,t=gi,t(actual)-gi,t(forecast) where gi,t= Gi,t/Yi,t is government spending as a share of GDP. The actual government spending comes from the October WEO of the following year. i-refers to country and t refers to time. question? 1. can you help me in attaching the codes of the forecast error approach on excel?

Hi, I would like to ask, does the MAD is similar with MAE? Because the formula looks the same.

@TheStatsFilesDawnWrightPhD 2 жыл бұрын

Yes, Mean Absolute Error MAE and Mean Absolute Deviation MAD are the same. Different authors use different names .

You can use any method to calculate the forecast values, e.g. moving average, exponential.

Check your sources. I think most authors divide by n.
