Mean of data after certain gap, example 1,5,9,...so on.
Milstein method is a technique for the approximate numerical solution of a stochastic differential equation
Geometric way to calculate min norm
Consider a linear system of equations Ax=b. If the system is overdetermined, the least squares (approximate) solution minimizes ||b−Ax||2. Some source sources also mention ||b−Ax||. If the system is underdetermined one can calculate the minimum norm solution. But it does also minimize ||b−Ax||
Drug induced liver injury prediction by ML Algorithms, feature selection and ROC analysis
Modified form of newtons method. It is faster and gives good convergence when we want to minimize a function in multidimension.
multinomial logistic regression is a classification method that generalizes logistic regression to multiclass problems, i.e. with more than two possible discrete outcomes.
Multiple Linear Regression, its Statistical Analysis, and Application in Energy Efficiency. Exploratory analysis; model selection; MLR; K fold cross-validation
faster multivariate newton method
The Nelder Mead algorithm is developed using a simplex, which is a generalized triangle in N dimensions, and it follows an efective and computationally compact scheme.
NMF in Matlab on Heart failure data sets
Data sets (and perhaps other utilities) to accompany Open Intro Stats with Randomization and Simulation
Principal Component Analysis (PCA) needs Polychoric correlation is suitable for ordinal variables with more than two categories, while polyserial correlation is appropriate when one of the variables is continuous. These correlations estimate the underlying latent (unobserved) continuous variables that give rise to the observed ordinal categories.
Polynomial curve fitting/ polyfit for covid-19 data set
Proximal gradient methods are a generalized form of projection used to solve non-differentiable convex optimization problems.

Simpson's rule uses a quadratic polynomial on each subinterval of a partition to approximate the function f(x) and to compute the definite integral
