In the example shown the formula in E5 is IFERROR INDEX names SMALL IF groups E 4 ROW names squared error which our regression software does for us automatically we are implicitly calculating the mean effect of each of the independent variables on the dependent variable in the presence of the others. If multioutput is uniform_average or an ndarray of weights then the weighted average of all output errors is returned. The least absolute deviation or L1 method is a widely known alternative to the classical least squares or L2 method for statistical analysis of linear regression models. MAE is calculated as The mean absolute percentage error also known as mean absolute percentage deviation is a measure of prediction accuracy of a forecasting method in statistics for example in trend estimation also used as a loss function for regression problems in machine learning. Some examples of these technologies are autonomy of unmanned mobile robots personnel and asset tracking personnel navigation and location based services.
