Jan 24, 2020 · The formula to find the variance of a dataset is: σ2 = Σ (xi – μ)2 / N where μ is the population mean, xi is the ith element from the population, N is the population size, and Σ is just a fancy symbol that means “sum.” So, if the standard deviation of a dataset is 8, then the variation would be 82 = 64.

Jun 25, 2021 · The explained variance is used to measure the proportion of the variability of the predictions of a machine learning model. Simply put, it is the difference between the expected value and the predicted value. It is a very important concept to understand how much information we can lose by reconciling the dataset.

Jul 16, 2021 · "Explained variance" is unbiased version of R 2 obtained by subtracting ( y − y ^) 2 ¯ from the numerator of R 2. Q1. Since "explained variance" is just an unbiased version of R 2, its different values carry same meaning as explained in question for R 2. Q2. Not sure why. They might just have missed it. – Rnj Jul 19, 2021 at 11:47 Add a comment
