Covariance (4 of 17) How to Calculate the Covariance? 

You are most welcome. Glad you found our videos. 🙂

You are brave to study abroad in a foreign language. Glad our videos ara of help. 🙂

so its not english?

Glad you found our videos! 🙂

Thank you.

The goal of these videos is to offer understanding. Often when additional context is offered it helps in that understanding.

It was added for clarification.

Not by a long shot. I am just a simple man struggling with the same problems everyone else sttuggles with.

We need to go back and understand what these data sets represent. If there is a relationship between the two data sets, then there will be a one-to-one correspondence and the sets will therefore have the same number of elements. If you pick two different sets that are independent of one another then it doesn't make a lot of sense to try and find the "covariance".

@@MichelvanBiezen okay , Thank You

The equations do require that the number of elements are the same. So you would have to randomly pick 5 out of the set of six.

Watch a few more of the videos in the playlist, (they are meant to be watched together), it may help.

You are welcome. 🙂

Thank you!

That depends on if you are using a sample (n-1) or the whole population (n).

@Michel van Biezen Okay thanks 🙏

We showed how to calculate the variance for comparison.

The playlists are arranged in the order in which they should be watched, unless you are looking for a specific topic.

@@MichelvanBiezen Oh, so I start with Kalman filter, mechanical, and then electrical right? I was planning to take both at the same time if it's possible.
