"Introduction" To some extent, E-commerce can be said to be the meaning of web analytics. This article explores one of the most common metrics for e-commerce sites: Abandonment Rate. Direct E-commerce analysis is less involved in this blog area, because I have been "immature" that E-commerce site analysis and our usual site analysis is not fundamentally different. After all, even if it is not an e-commerce site, it still has one (or more) can be quan

This statistic is affected by all constraints, such as I/O, number of users, cache size, complexity of the request, and so on

1. Confusion Matrixis a confusion matrix of two types of problems in which the output uses a different category labelCommonly used metrics to measure classification performance are: The correct rate (Precision), which is equal to tp/(TP+FP), gives the ratio of the true positive example in the sample that is predicted to be a positive example. recall Rate (Recall), which he equals to tp/(TP+FN), gives the true positive example of the predi

When doing jmeter testing, if you want to count the disk IO read and write speed, then it is very easy to think of the perfmon Metrics collector this plug-in, but the specific use of the process has the following needs to be noted.1, such as first, need to choose monitoring Read or monitor write, such as to monitor write so long select Writebytes, choose this statistic result has unit, at a glance.2, Filesystem filter must be designated here to monito

Size metrics for Java projects: Micro: Just a person, even half-day work in a few days to complete the software; Small: A person within six months to complete the 2000 lines within the program; Medium: 5 people in more than 1 years of time to complete the 5000-50000-line program; Large: 5-10 people completed in two years of 50000-100000 lines of procedures; Very large: 100-1000 people participated in a 4-5-year completed softw

Open one project/solution in Visual Studio (premium) and use the "analyze> calculate code metrics for solution" menu item to generate the code metrics report. Once calculated, the data can be exported to a data sheet for further analysis (e.g. counting the number of methods whose cyclomatic complexity is greater than 25 ). Note: Cyclomatic complexity (or conditional complexity) is a software metric (meas

Use Windows performance monitor to monitor common SQL Server metrics As mentioned in the above article, Win's Performance Monitor is an essential tool for monitoring database performance. Next I will introduce some common monitoring metrics, which are nothing more than disks, CPUs, memory and other hardware operating indicators include database locks, user connections, and parameter indicators that need to

Performance Metrics)Before we start to travel this book, I must first understand the performance indicators of this book and the results to be optimized. In chapter 2, we will explore more performance testing tools and performance indicators, however, you must use these tools and understand the significance of these performance indicators.The performance metrics of applications vary depending on different b

Skewed classesSkewed classes: The number of a species is much higher (or less than) another class, that is, two extreme cases.Predicting the classification model of cancer, if there is only a 1% classification error on test set, at first glance is a good result, actually if we predict all Y to be 0 (that is, none is cancer), the classification error is 0.5% (because the ratio of cancer is 0.5%). The error is reduced, is this an improvement to the algorithm? Obviously not. Because the latter meth

For example, it doesn't tell you where third-party content is loaded faster. But from the user's point of view, these are not problems.The author makes a detailed division and explanation of the response time and page load time of the website, I believe you have a

What this article brings to you is what are the metrics for precedence in CSS? The use of CSS weights introduced, there is a certain reference value, the need for friends can refer to, I hope to help you. I. BACKGROUND There are three main features of CSS: cascading, inheritance , priority . While we are defining styles for CSS, it often appears that two or more rules apply on the same element, and the effect that the element ultimately renders in th

SP are abstract pixels, and Android automatically converts the values of the SP and DP to pixel units at run time.Official conversion formula: pixels = DPS * (ppi/160), the coefficient is ppi/160, for example, for the above 1080p screen, px=dp*441/160, draw a 320dp horizontal line, will occupy the screen of 882/1080On the 160dpi screen (that is, HVGA, since the general pixels are squares, the resolution is the same in the general direction), the conversion factor of DP to PX (pixel density) is
