In first question,there is no need to calculate variance of second estimator 17:55 because it is biased one ,am i right? For efficiency we chose unbiased estimator isn't ?
The explanation was really great. But I got stuck at one place...I couldn't quite understand how you decided which x function is for mu and which is for sigma in the second last example. Please sir explain once more
Because if you want to calculate Sigma square then summation of x square must be known it means if you are given Sigma square so x square is known so to know mu summation of x is sufficient.
what an explanation sir👏👏👏❣❣❣
sir please upload unit 6 hypothesis testing in MTH 302....as our exams are approaching

Some times it is possible that all the estimators are biased then we look for the the one with least variance .
@@Sanonlineclasses okay sir thanks
42:10 i havent understood it sir how it has changed to sumation from product
If bases are same then exponents are added.
18:13 ,lets assume var(t3) < var(t1) < var(t2) , but t3 is biased so in this case also t1 will be best estimator right ???
Using the term best estimator is not that appropriate rather it should be most efficient.Selection of best estimator depends on situation.
Thank you sir ❤

Can you put time stamp
Sure, sir @@Sanonlineclassesit's 47:00

@@Sanonlineclassesthanks, sir. Understood.
But if lamda was 0, how comes you are calculating variance of X3 and it's 0 in t3
Can you put the timestamp?
Nice Blood example for sufficiency 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
Presence of VITB attend here💌
He was a teacher at LPU🔥
Sir please unit 5 start kijiye
Are you talking about First semester?
