How to calculate the explained variance per factor in a

To illustrate, the following R code creates some data, computes their covariances, and obtains the least squares coefficient estimates solely from that information. It compares them to the estimates obtained from the least-squares estimator lm .

Where r is the correlation coefficient of X and Y, cov(X, Y) is the sample covariance of X and Y and sX and sY are the standard deviations of X and Y respectively. NumPy provides the corrcoef() function for calculating the correlation between two variables directly.

How to calculate the explained variance per factor in a

In probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its mean. Informally, it measures how far a set of (random) numbers are spread out from their average value. Variance has a central role in statistics, where some ideas that use it include descriptive statistics, statistical inference, hypothesis testing, goodness of fit, and

In statistics, Bessel's correction is the use of n − 1 instead of n in the formula for the sample variance and sample standard deviation, where n is the number of observations in a sample.
