In statistics, mean absolute error (MAE) is a measure of errors between paired observations expressing the same phenomenon. Examples of Y versus X include comparisons of predicted versus observed, subsequent time versus initial time, and one technique of measurement versus an alternative technique of measurement. MAE is calculated as the sum of absolute errors divided by the sample size: WebOct 16, 2024 · Introduction. This article will deal with the statistical method mean squared error, and I’ll describe the relationship of this method to the regression line. The example consists of points on the Cartesian axis. We will define a mathematical function that will give us the straight line that passes best between all points on the Cartesian axis. highest interest bearing bonds https://sofiaxiv.com
