We all know that {Xi, I =, 3 ...}, assume that the sample points are subject to a single-peak Gaussian distribution, the maximum likelihood estimation parameter expression is:
Expected: variance:
However, have you noticed that the variance
Something summarized at some time last year, there was a question about "More evict skills" during this provincial competition. I feel that these small knowledge cannot be ignored. I will post it and share it with you ~
Phase Division
Division,
Evict
Evict, also known as "equivalent algorithm"
The question about the denominator is actually how to find the largest denominator of the numerator. This method is introduced in chapter 9 arithmetic, which is called "More evict". The mathematician
The first problem is the requirement to implement a program that automatically generates subtraction arithmetic topics for pupils. You can extend it later as a website or Android app or iOS app or Win10 app.My thinking is quite simple. The
I. Moving Phase Division (EuclideanAlgorithm)
Definition: the so-called "moving phase division" refers to dividing the given two numbers by a large number by a small number. If the remainder is not zero, the remainder and a smaller number form a
From Scala wizard Chapter 1 functional objects
With the basic Scala knowledge gained from the previous chapters, you are ready to explore how to design objects with more comprehensive features in Scala. This chapter focuses on defining functional

More subtractive loss SurgeryMore subtractive damage, also known as "equivalence algorithm"On the question of numerator, the essence is how to find the numerator, the denominator greatest common divisor. This method is described in the nine chapters
In statistics, the maximum posterior probability (MAP) estimation can be used for point estimation of unknown parameters. It is similar to the Fisher method of the maximum likelihood estimation maximum likelihood (ML, however, the maximum posterior
