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-

1. The six-layer structure of the block chain
Data layer: is a block + linked list of data structure, essentially a distributed block chain
Network layer: Peer-to-peer network.
Consensus layer: To develop the mechanism of acquiring currency in the block chain. For example, Bitcoin uses POW (Proof of work work proof mechanism): the better the computer's performance, the easier it will be to obtain monetary rewards. There is also the POS (Proof of Stake): a concept similar to a public divid

The mean value represents the size of the DC component in the signal, expressed in E (x). For a Gaussian white noise signal, its mean value is 0, so it has only the AC component.
2 square of the mean value
The square of the mean, denoted by {E (x)}^2, represents the power of the DC component in the signal.
