From the history, I found that you had add the definition for independent variables. It looks good. The following are my suggestions for editing.

Content
1.     Introduction

I think the introduction is not clear right now, and the link between the paragraph and the paragraph is not strong. Normally the introduction started to explain the importance of the topic. Then introduce the limitation or the challenges of the topic. Finally, introduce briefly some applications. Although the introduction did contain some of the above points, it is not clear enough. Therefore, I think establishing a clear article structure or adjusting the order of paragraphs can help others to read more easily.

2.     Definition


 * I think the definition would be more clear to explain what is “I” ?


 * “Definition for independent variables” seems to be the general definition of the topic. Therefore, I suggest moving this paragraph to the beginning of this section. In addition, I also suggest changing the font of variables A, B, C and the probability P in this paragraph to make it separate from the text. For instance, Suppose A, B, C are three events. If P(AB) =P(A)P(B)…

3.     Examples

More explanation in the example will be helpful for people who are not familiar with statistics.

4.    Machine learning

I would suggest adding more explanations or examples in this section. If there is scare information to add, I suggest taking it as one of the examples.

Conclusion
Overall, I think there is still a lot of room for improvement in this article. More description and explanation can help more people understand this article.

Good luck for you editing. Hope everything goes well to you. :)    C.Hua Wang
