| Dec 22, 2015 at 1:23 | comment | added | whoisit | sorry I don't know how to type the math symbol, you know we have a formula instead of use s directly, I will add the picture in my question | |
| Dec 22, 2015 at 1:17 | comment | added | whoisit | many thanks for your detailed answer. It really helped a lot. One last thing I don't get is, let's say we estimate the sample deviation s, then we can from the model of W^=β0^+β1^×1.75 we have one response value w^ when predictor is 1.75, then we can say 95% the true weight value will be from w^-2s to w^-2s (I know the t value should not be 2,as the df is n-2, but let's have it for convenience). why we still have some complicated formula like s\sqrt{\frac{1}{n}+\frac{{(x*-x)}^2}{(n-1)S_{x}^{2}}}, why don't we just simply use s? | |
