So how can we estimate the standard error of beta hat with only 1 sample? It seems like you need access to mutliple samples to get this info? or do we use sub samples from within our 1 sample that we have?

Thanks for the video! One question: then what distribution and what test should we use to measure the critical score or p-value for regression coefficient?

Can one use linest to calculate standard error of slope and intercept?

I have been trying to find how to calculate the standard errors of regression coefficients, but sadly most of the tutorial only show how you can do that with tools (excel, etc.). While I need to create my own program that can the linear regression. Any clue / suggestion?

Thanks Rizki. The purpose of this video was to communicate the intuition of the standard error, as understanding the intuition first makes learning the formulae (contained in any standard textbook) much easier to understand and apply. I plan to make a more technical video on the standard error shortly, so hopefully you'll find it handy. All the best Dave

Did you try to see a solved problem in your text? It is a very straight forward process and most of it can be done on Ti-84 or Excel.

Then, if we can write mean +- SD, is it similarly logical to write: y = (Beta +- SE)x + constant ?? Not for actual writing, since it is non-standard. Just want to check if my understanding is correct..

Given that we only supply one data-set(training) to a Regression problem, where does the data for re-sampling and in turn re-estimation of 'beta' come from ? Is the supplied training data assumed to be the population and re-sampled from ?

How did you calculate how far beta was from 0?

It will be great if you can provide an intuitive explanation of standard errors of coefficients. The title give such an impression.

how does one directly calculates that Beta is 5 standard errors away from 0?

Oww why do some don't explain the reason of finding standard error for regression analysis Thanks

@tanguyvranckx1134 5 ай бұрын

Here's my take: Suppose that our standard error is 0.2 for an estimate of B, ^B, that = 1. In that case, our estimate is 5 standard errors away from zero, which is what we assume the true B is under the H0. That’s pretty far away from the 0, far enough to suppose that this estimate of 1 is not due to the characteristics of one particular sample. There is a very decent chance that we will be able to reproduce this estimate through another sample.

First of all, the voice was not as what I expected. I mean, look at the thumbnail... WTF?? I expect a more cheerful voice. Second, which part of this is simple???? Damn I feel stupid. Don't judge a youtube video by its thumbnail.
