: Krumbach a reliability coefficient is the most commonly used reliability coefficient at present. The formula is: a= (k/k-1) * (∑SI2)/st2)Among them, K is the total number of the items in the scale, SI2 is the variance of the problem in the first question, ST2 is the variance of the total score of all the titles. It can be seen from the formula that the evaluation of a coefficient is the consistency between the scores of each item in the scale, which belongs to the intrinsic consistency coeffic

Application chapter use), DTN iqfeed (Trial account, Used to quantify the download of high-frequency data in transactions) all the development tools and environments, libraries and so on are open source and can be obtained and downloaded free of charge from the Internet.2. Introduction to the contentThis tutorial introduces the basics of using Python for data

analysis, this is mainly because of the lack of a demand system that can be truly understood and communicated by all parties and gradually refined. Currently, most users use the document system of structured analysis (including data flow charts and data dictionaries ). This document system originated in 1970s. At that

A few years ago, only Sendmail was available for free mail servers in Linux. However, due to the Sendmail defect, some developers have developed several other mail server software. Currently, the free email server running in Linux, or the MTA (Mail Transfer Agent), has several options: Sendmail, Qmail, Postfix, exim, and Zmailer. This article will describe the ch

Analysis of the Process of neutral performance tuning in software testing-Linux general technology-Linux programming and kernel information. The following is a detailed description. Performance Tuning is undoubtedly a huge topic and a very important part of many projects. It is well known that performance tuning is difficult. After all, performance tuning covers too many areas, in this article, let's take a

time is directly manipulating the data in memory, is not CPU performance bottlenecks, it is necessary to look at the CPU usage and queue length. If CPU usage is high, CPU bottleneck, CPU usage is not high, queue is very long, CPU is blocked, need detailed analysis reason (back up analysis). CPU usage is low and queues are not long. Non-CPU bottleneck Memory: Hi
