Brief introductionEditThe general form of the Box-cox transformation is: The new variable obtained by the Box-cox transformation in the formula is the original continuous dependent variable, which is the transformation parameter. The above transformation requires the original variable value is positive, if the value is negative, you can first add a constant to all the original data to make it positive, and

On July 13, Russ Cox shared "The Future of Go" on Gophercon, reviewing the history of the go language and looking forward to go 2.
Rob Pike, Robert Griesemer and Ken Thompson discussed a new programming language for a while, and on September 25, 2007, Rob suggested that it be named Go.
Later, Russ Cox and Lance Taylor joined
Cox Proportional risk regression model (Cox's proportional hazards regression model), referred to as Cox regression models. The model, proposed by British statistician D.r.cox in 1972, is mainly used for prognostic analysis of tumors and other chronic diseases, as well as for etiological exploration of cohort studies.h (t/x) =h0 (t) exp (β1 X1 +β2 X2 + ... +βp Xp) H0 (t): The benchmark risk function is the

In fact, we can leave aside all network protocol-related knowledge. This is just an extremely common one-way linked list operation, and the logic is not complicated. But let's look at how top hackers think about coding and compare the code they have written, how many times of data processing is done with a simple for loop without further thinking about the rough and unreasonable aspects? Do you have an in

There is also open-source office software OpenOffice.org, which is an office software package competing with Microsoft's office. "There are many opportunities to use open-source software outside the Linux World," said Alan Cox, a Linux expert. "OpenOffice, Firefox, PHP, Perl... many Web-based programming tasks on Windows use open tools."
If you use open-source software, you will encourage and promote others to use it. wh

Phil Cox, chief consultant of SystemExperts, said: "The operating system does not have to spend money when using Linux, but if you choose Windows, you need to pay Microsoft license fees. Therefore, in terms of costs, linux is the best choice, and on any physical hardware platform, the performance of Linux is always about 25% faster ". However, 51CTO believes that the operating system of which server is better still needs to be determined based on the
