, the sample x obeys the normal distribution, the original assumption sample x obeys the normal distribution, and the distribution parameter is estimated by X. The output parameter h equals 0 or 1, if h=0, the original hypothesis is accepted at the significant level 0.05, the X obeys the normal distribution, and if 1, the original hypothesis is rejected at the significant level 0.05.
Returns the P value of the test, rejecting the original hypothesis when the P value is less than or equal to the

enterprises, IT loses 5 hours of productivity.
In the data center and telecom fields, technical staff will also create additional risks when they accidentally unplug some plug that should not be pulled. Assume that a VoIP switch or a key server is accidentally disconnected. As I have reported many times in recent news, what if a device with critical information gets disconnected? How does the network administrator know who is on the network? How are these operations recorded?

two vertices are the values of the similarity metric function of two samples.

Purpose
What is data visualization?
Data Visualization stage
G2 positioning and planning
Purpose
I have been engaged in data visualization for 2 or 3 years. I found that most people's perception of data visualization is to draw charts. Therefore, I want to write some articles on Visual Framework Design. These articles
