How to calculate and when to calculate covariance step by step with example by hand | Neeraj Sharma

To the point and easy explanation in the Hindi language of when we need to calculate covariance and how to calculate using the covariance formula. All explanation is step by step by hand with an example solution. I hope it will be helpful for many.

Thank u so much.I m so worried about covariance topic but your video is very helpful for me.

Thanks

Formula galat hai
N hona chahiye
N-1 nhi

[@krishnatrivedi5579]

N-1 is for Sample and N is for Population

Thank you so much.!

Thanx bro

[@hot_videos_000]

amazing 👍👍

[@arabshahrehman5739]

Thanks but I'm still in a confusion that how I will know data is increasing positively or negatively in this question I can't clear this

[@bhagyaaundhakar5168]

Where is n and where is n-1

[@jayvijay3039]

Bhai video wapas banao n aaega sirf. N-1 nahi

Normalization by N-1 is "correct" in the sense that the resulting estimator is unbiased. This means that if the sample number goes to infinity the covariance estimate approaches the true covariance.
If you would normalize by N, the estimation has (slightly) lower noise but is biased, i.e. gives the wrong result if N approaches infinity.
Note, that the above only applies if you don't know the mean value: In case you would know the mean values, normalization by N is correct (you have to plug in the correct means in the formula as well, of course).

Where is gorkhalia army scene not added???? Sam is nothing without gurkhasss

[@siddharthbirmecha9201]

n-1 nahi hota hai sirf n hota hai

[@fairytail1405]

Yeah I was thinking the same, in my book it is written n and he was saying n-1 so I really confused 🤔 but the video gave an idea of how to do the sums 🙃
