Chi-square test is a hypothesis test method for counting data with a wide application. It belongs to the category of Nonparametric test, which mainly compares the correlation analysis of two and over two sample rate (composition ratio) and two categorical variables. The fundamental idea is to compare the theoretical frequency with the actual frequency of the degree of coincidence or goodness of fit problem. (More reference: chi-

Go-ethereum
The Go-ethereum client is often referred to as the Geth, which is a command-line interface that executes the complete etheric square node that is implemented on the go. By installing and running the Geth, you can participate in the real-time network of the front desk of the ether and do the following: Mining the real etheric currency transfer funds between different addresses create contracts, send deals to explore block history and many
The Bucketmethod is a method of dividing a row of objects or planes into buckets, each of which maintains its own internal information to achieve the purpose of efficient computation.where the square partition (sqrtdecomposition) is a row of n elements each square root n points in a bucket to maintain the method of the collectively. Such a segmentation method can reduce the complexity of the operation of th
1. root mean square error,It is the square root of the ratio of the sum of squares of observed values to the true value of observed number N,In actual measurement, the number of observations N is always limited, and the true value can only be replaced by the most trustable (optimal) value. the Gini error is very sensitive to the extremely large or extremely small error in a group of measurements. Therefore,

Preface
This is a teaching article, mainly for understanding the Ethernet square and block chain technology used. It was a technical curiosity to write this article.
Block-chain technology began to use virtual currency, in which Ben Cong started the bitcoin block chain in January 2009. Bitcoin was born, through several rising prices let block chain technology is famous. Block chain is a new application mode of computer technology such as distributed
The rectangle has two attributes: length and width. There is also a way to set the length and width, and a way to calculate the area.As shown belowPrivate int length;Private int width;Public void setLength (int lenght ){This. length = lenght;}Public void setWidth (int width ){This. width = width;}Public int getArea (){Return this. length * this. width;}If Square is a subclass of a rectangle. To ensure that the squ
7.5 Given, squares on a two-dimensional plane, find a line that would cut these the squares in half. Assume the top and the bottom sides of the square run parallel to the x-axisThis problem gives us two squares, so let's ask for a straight line that says the two squares are divided evenly into two parts, assuming that two squares are parallel to the X axis. So we first need to know what kind of straight line to divide a
Total Square Number(number.*** (C/cpp/pas), 1000MS,128MB)"Problem description"A number if it is the complete square of another integer, then we call this number a complete square (Pefect sqaure), also known as the square number.Small a thinks that all the squares are very perfect ~So he gave the little b a task: Multip
= (10000-2n) x10000 + n*n = ((10000-n)-N) *10000+n*nNotice that as long as the number of 9 is greater than or equal to the number of non 9, you can use this method to quickly calculate the square numberIn this way, you can convert the square of the high number to the square of the low number. For high-level numbers, all you need is add and subtract and keep the

Ethernet as a digital currency of the operating system, it is obvious that it will also have a wallet-like client program, to provide management account balances and other functions. We know that storage (or binding, affiliated) account of the ether, in the code with the address type variables exist, so the ability to manage multiple Ethernet square accounts should be one of the basic functions of the client program. This article starts with the code

Details of variance, standard deviation, and mean square error, and variance error detailsVariance
In Baidu encyclopedia, variance is interpreted as: (variance) a measure of the degree of discretization in the measurement of random variables or a set of data in probability theory and statistical variance. In probability theory, variance is used to measure the deviation between a random variable and its mathematical expectation (that is, the mean. The
