Dear Support,

at video Measure for in-sample at 00:42 the difference is
100 not 50

Dear Support,

In the video of Polynomial Regression at 1:53 the function is
np.poly1d not np.ployd1

Thanks

In the video of Analysis of Variance at 3:04 the second commad should be

groupby (["make"]) because there is a little mistake in it.

In video Descriptive statistics at 1:32 you will notice there is a missing "}"
closing curly bracket.

Thanks

Dear Support,

I descriptive statistics video plt.xlabel() is mentioned twice instead of ylabel .

Dear Support,

in the Binning in Python the bandwith formula you divided by 4
I think it should by divided by 3 because [low,med,large] only 3 bins
also I remake it.

Thanks

1 - There is something wrong with the user's session management, when browsing pages the account name on top-right always change to "login register" links;
2 - The "claim you offer" button is not working, there is an error in its loading;
3 - The link to open the account options (top-right) is kind of small, I always click on the name thinking that is going to open a menu and the page is redirected to the Dashboard;

More advanced courses is needed on BIG DATA, Cloud Computing and on Relational Databases.

Calculus course with ML algorithms

....as I have a feeling that I was using visualization in the data analysis course, but not the other way around. Also I think the analysis course is more intermediate

It is quite annoying that I have to open links after links to play short video clips (1-5 mins) for each topic. Any way to play the videos continuously like other e-learning platform

This is a great library for learning Data Science / Big Data.

And the availability of the iOS app for learning will be really helpful to some of us working professionals, who want to make this change towards Data Analytics.

I saw a lot of courses are in Python 2. Please introduce python 3 and update the course contents

I think, it'd be easier to maintain & use the account with multiple options available. it's good that you provide multiple email options, but it'd be great if your provide to login using username. What is the use of a unique username if it can't be used instead of your email id for login? I changed my email id & was unable to login after that as your database didn't receive my other id. So, that made me lose all my progress with the previous account. Thank you!

I'm not able to write the exams, when I clicked the final exam button, it can't move to next page. It remains in the same page
