I'm happy you liked it :) I'll do my best to start covering machine learning with TensorFlow next week

easy to follow along and good content as well

Thank you Derek! You're awesome !! Is there any non-linear regression tutorial?

You shouldn't have substituted the std error value of 0.262 for the coefficient of x1, but rather the eval coefficient of 0.2687 because that is what our independent variable is. Let me know if there is something wrong with what I have said.

I'm also interested in a reply to this. I immediately caught this too but I want to make sure I'm not misinterpreting something.

can you use this for multivariate linear regression?

Thanks Derek , but I really wait for calculus and linear algebra in one video

I'll see what I can do. Linear algebra is very doable. Calculus would be a very long video

un grand merci (:

C'est un plaisir pour moi d'aider

can you please make tutorial a bout scapy in python

It was very helpful to watch, just one comment: Usually y is the dependent variable, so your variable names in the beginning are the wrong way around. In this case it does not matter because it was only one independent variable, but technically speaking you tried to estimate the effect of evaluation results on beauty there The same later on (total_bill got explained by tip), which is why I imagine it didnt work with binary variables.

can someone tell me why I am adding a column of 1 to X?

Greetings, Derek Banas

Inventory analysis please

Thanks for this intro to linear regression. I think "sex" and "smoker" didn't work because of their "categorical" nature as opposed to other "numerical" predictors.

Yes that is most definitely true. I could have gotten them to work, but I thought it didn't matter that much

@@derekbanas from real life examples - it does not matter what model are you choosing if you are an expert you can combine enough compexity and at least moderate results. Or if you are black boxing you do not care what model is. There is no such rule that catrgorical variables will not be predictive. In general education, wealth, family status, age, gender, Credit score, location are preferable

Sooo... "Expressions" or "Regressions" now?
