In the example 1 of parameter hypothesis test under 0-1 Population Distribution, I used the lookup table method to analyze how to perform the parameter hypothesis test. In this article, we will use the SPSS tool to directly calculate the results.
Speaking of SPSS, there are actually no strangers. I used SPSS 13 before and was not acquired by IBM at that time. No
some guidance, I understand it. In fact, I have been thinking that the conversion process of the decimal number should have a mathematical formula derivation, which leads to the constant conversion of the decimal number, if you focus on the binary number, it's hard to understand. (There may be a mathematical formula, but instead of looking for a formula 15-> 10-> 4, it is easier to understand the process of directly observing the changes of binary strings)

Opencv experiences (1)
The second chapter of learning opencv mainly introduces some common and interesting functions and data types, so that students at the beginning are more interested in image processing, although I do not understand the internal experiment of the function and the meaning of some defined constants, I am still very happy after learning Chapter 2. At least I know some basics of image processing, such as contour processing;

Os._exit () and Sys.exit ()Os._exit () vs Sys.exit ()OverviewPython's program has two exit methods: Os._exit (), Sys.exit (). This article describes the differences and choices between the two approaches.Os._exit () will terminate the Python program directly, and all subsequent code will not continue to execute.Sys.exit () throws an exception: Systemexit, if the exception is not captured, the Python interpreter exits. If there is code to catch this exception, the code will still execute. Catchin
