Compute the variance of the PDF. f(x) = xe^{-x} for x \geq 0 and f(x) = 0 elsewhere; the mean = 2. Let X be a random variable with the following probability distribution. Complete the following. A) Find the expectation E(X) of X. B) Find the variance Var(X) of X. ...
Hi, I am trying to compute the (bures) wasserstein distance between gaussians of different dimensions. Mainly I was checking on the tutorial shown here where they try to find couplings of datasets with different sizes but of the same dim...
To compute the covariance and mean, a so-called training set of measurements is needed, which ideally should include all relevant spectral features. For the dissemination of IASI PC scores a global static training set consisting of a large sample of measured spectra covering all seasons and all ...

Now, we compute the covariance matrix for the centered data: Then, we compute and sort the eigenvalues: and the corresponding eigenvectors: To perform PCA on the data with the number of PCs , we define: Now, we can compute : 4.1. Inverting PCA We performed PCA on the data. Let’s now...
