I have seen this … WebAug 18, 2024 · Both MAE and MSE can range from 0 to positive infinity, so as both of these measures get higher, it becomes harder to interpret how well your model is performing. Another way we can summarize our collection of residuals is by using percentages so that each prediction is scaled against the value it’s supposed to estimate.

WebWe can use the symmetric and itempotent properties of H to find the covariance matrix of y^: Cov(y^) = σ 2 H. As usual, we use the MSE to estimate σ 2 in the expression for the covariance matrix of y^: Cov(y^) = (MSE) H = (SSE / DFE) H . The square roots of the diagonal elements of Cov(y^) give us the estimated standard errors of the ... WebOne supposed problem with SMAPE is that it is not symmetric since over- and under-forecasts are not treated equally. This is illustrated by the following example by applying the second SMAPE formula: Over-forecasting: A t = 100 and F t = 110 give SMAPE = 4.76%
The mean absolute error is one of a number of ways of comparing forecasts with their eventual outcomes. Well-established alternatives are the mean absolute scaled error (MASE) and the mean squared error. These all summarize performance in ways that disregard the direction of over- or under- prediction; a measure that does place emphasis on this is the mean signed difference. Where a prediction model is to be fitted using a selected performance measure, in the sense tha…
