The success rates of Cupid’s arrows

I advised a master’s student to use the binomial probability formula to determine the likelihood of attracting the affection of 15 girls, with Cupid’s success rate at 0.7. The analysis shows that the highest probability of success occurs when 10 girls reciprocate love, with a probability of 0.33.

Estimating the sparse inverse covariance matrix (precision matrix) by Graphical Lasso (with Python implementation)

Graphical Lasso, also known as GLasso, is a statistical technique used for estimating the sparse inverse covariance matrix (precision matrix) of a multivariate Gaussian distribution. Here, Sparsity means that many elements of the matrix are… Estimating the sparse inverse covariance matrix (precision matrix) by Graphical Lasso (with Python implementation)
