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
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

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
Some SIM cards are not preset with the VoiceMail number at the factory, but the operator requires that the preset VM number be read from the mobile phone according to PLMN. This section describes how to preset VM number in xml format and how to allow users to modify and remember their choices. The priority of VM number is: SIM card reading> User Settings> xml preset. When you modify the voice mail number, the SIM card is preferentially stored. If the
Some SIM cards do not have a preset voicemail number at the factory, but the operator also requires the ability to adaptively read the preset VM number from the phone according to PLMN. This article describes how to preset VM number in XML, and how to allow users to modify and remember the user's choices. VM number uses a priority of: SIM card read > user settings >xml preset. When the user modifies voice mail number, the SIM card is first stored. If
