I did this for a project last year and waTched this video just to verify I actually did it correctly lol I’m so scared of having done things wrong so I really appreciated this! Thanks!
Hi, that’s a great question, the shown approach in the video is just to show the function in action, but in a real-world situation preceding the fillin of replacement values by a groupby of the Y column values may be good way to fillin values by also considering the context of the class from which it belongs to.
Professor, I'm trying to understand where to use sql in data science, I already understand python, ARIMA, and sql language too, but how to use it? Could you explain this to me please?
Hi, you can use it to retrieve/query/summarize data from a database, which lies at the core of data science where it will then be used for EDA, model building, model interpretation, etc.
