inverse t distribution

One of the three most important features of the variable distribution is fat-thin (the other two: Singlemode-multimode; symmetry-biased), Cauchy distribution and normal distribution are very confusing distribution curves.Cauchy distribution is also

Probability theory is a branch of mathematics that studies the law of random phenomena. Its origins in the 17th century century, at that time in the category of error, demographic, life insurance, need to collate and study a large number of random

Exponential family (exponential distribution family) is a common concept, but its definition is not particularly clear, today look at the wiki content, have a general understanding, first and share with you. This article is basically the translation

This document is a PDF format directly converted from the Internet, Introduction to MATLAB mathematical statistics toolbox1. OverviewThe Mathematical Statistics toolbox of MATLAB is a relatively simple tool in the MATLAB toolbox. The mathematical

Norm indicates a normal distribution:rnorm (x): indicates the generation of a random x normal distribution sequence, randomdnorm (x): the probability density functionof the output normal distribution, density function ———— plot (dnorm (x)), to draw

The probability density function of the multivariate Gaussian distribution and the element Gaussian distribution is given directly:　　μ is a D-dimensional mean vector, Σ is a dxd covariance matrix, we only consider positive definite matrices (all

creation and manipulation of vectors C () create vector length () mode () to determine the type of vector rbind () by row combination Vector Cbind () by column

How C + + generates random numbers: Here is the rand () function, the Srand () function, and the C language/c++ does not have its own random (int number) function.(1) If you want to generate random numbers without setting a range, you can just use

First, the basic principles of statistics12 Sample t Test Condition: ① Both obey normal distribution, ② two population variance is equal, namely variance homogeneity.2 pairs of T-Test conditions: The difference of the overall normal distribution can
