gamma distribution in r

IntroductionThe generalized inverse Gaussian is a kind of rich probability distribution, and its parameters are derived from some classical useful distributions when the parameter is a certain value.Generalized inverse Gaussian distribution

1. Dissociation data and discrete distributionDissociation data is usually data that can only be represented by integers. For example, the number of people in a province, the number of planets in a unit volume in the universe, etc.1.1 The discrete

Use C ++ tr1 to generate a random number Original: [Original ENGLISH]Translation: Orbit)Introduction This article describes how to use the random number generation function provided by C ++ tr1 (C ++ Standard Committee Technical Report 1 ).In

In the summary of the principle of spectral clustering (spectral clustering), we summarize the principle of spectral clustering. Here we make a summary of the use of spectral clustering in Scikit-learn.1. Scikit-learn Spectral Clustering OverviewIn

There are many statistical distributions, which are basically described in R. Due to their limited capabilities, we have selected a few common, more important, and simple descriptions of each distribution definition, formula, and presentation in

In the R language, different distributions can be generated for experimentation and learning.In R, the probability function is shaped like ①:where the first letter denotes one aspect of the distribution that it refers to:D = density function

R Language Data Analysis series four --by Comaple.zhangWhen it comes to statistical analysis, we can't leave random variables, so-called random variables are mathematical models that mathematicians build to better fit the real-world data. With her,
