Degrees of freedom part 1

[jagratigoyal]

this is indeed the most non-explained topic in Econometrics and you have made it so easy. I hope to have more teachers like you.

perfect! I don't know why people tend to make things as complicated as possible in any book or lecture. Thank you for intuitive explanation as always!

Dear Professor - excellent materials. I do not know if you can kindly do a video to collect instances how Degrees of Freedom varies in statistics and in what way. For instance one can regress a lot of variables in a bulk model and potentially reduce the degrees of freedom

Thanks! quite useful for a business researcher....

Why is it necessary to know the degrees of freedom for a chi-square test of association in order to find the correct p number from a table ?

[alexisglennespina]

Thanks for this. It's very true that this is an ignored concept in statistics. You just start plugging in values for different formulas without truly understanding the meaning and intuition behind it.

Thank You for such a nice explanation.. just have a doubt ; is degree of freedom= variables- constraints in all cases..

I thought it was y=mx+b, or is that an american thing?
