Multinomial distribution
The corresponding multivariate distribution can be obtained by extending the two-yuan case of two-yuan distribution to multiple variables.
First, the Bernoulli distribution is extended to the multivariate hypothesis for the discrete variable x x, there may be K K, then x x observation is repres

1, what is the index distribution family 1.1 basic descriptionExponential distribution is a kind of important distribution family, in statistical inference, exponential distribution family occupies an important position, which is widely used in various fields. Many of the statistical distributions are exponential

Requirement background for large companies, there must be a site or configuration file updates from time to time, and the use of the machine is certainly a lot of units, less than a few, more than dozens of or even hundreds of Taiwan. Therefore, automatic synchronization of files is critical.

Introduction
Poisson distribution evolved from two distribution.
Two distribution that is, if the coin positive upward probability of p, toss n times coins, this n times the coin toward the K-time (k
P (k) =CKNPK (1−p) n−k (1) p (k) = C_n^kp^k (1-p) ^{n-k} \ \ \ \ \ \ \ \ \ \ (1)
the expectation of the coin upward is:
E (k) =PN (2) e (k) = pn \ \ \ \ \ \ \ \

"Fitting of distribution"
The distribution function of the sample (also known as the "Experiential distribution function") is stacked with the distribution function of a theory (such as the normal distribution) to be compared.For example:
Score = Xlsread (' Examp02_14.xls ',

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 called Cauchy-Lorentz

This involves a mathematical probability problem.two meta variable distribution: Bernoulli distribution, is 0-1 distribution (such as a coin toss, face up probability)Then the probability distribution of a coin toss is as follows:Suppose the training data is as follows:So, based on maximum likelihood estimation (MLE),

This article mainly wants to explain three questions:One is the numerical characteristics of the sample, The second is the difference between the variance of the sample and the mean of the sample , and the third is how to construct the sampling distribution.AFor simplicity, suppose there is a general ξ~n (µ,σ2) of the normal distribution, imagine that we randomly extract N samples, ξ1, ... Ξn.There is a sample mean and sample variance at this point.T

When I was in college, I always thought statistics was difficult and almost hung up.After work only found that the difficult is not statistics, but our textbooks are not well written. Compared to advanced mathematics, the concept of statistics is much easier to understand.Let me give you an example of what is Poisson distribution and exponential distribution? I'm afraid most people are not clear about it.I

OverviewThe event distribution mechanism in Android is the distribution and processing of events between view and ViewGroup. The interior of ViewGroup contains many view, and ViewGroup inherits from view, so ViewGroup itself is also a view. The event can be viewgroup to its child view and processed by the child view, and ViewGroup itself can handle the event. The following is a detailed analysis of the view
