# Thread: Pleease help!? Filling in "blanks" in Regression Output

1. ## Pleease help!? Filling in "blanks" in Regression Output

Hello!

Can someone please explain, I need to fill in the blanks marked
They provide this info in a row:
Coeff:-9074.674
Std.Err: ??
p-value: 0.000
95% Conf.Intervall: -13272.86, -4876,485

How do I calculate Std.Err & t-stat here?
Best Regards

Hi! We are glad that you posted here! This looks like a homework question though. Our homework help policy can be found here. We mainly just want to see what you have tried so far and that you have put some effort into the problem. I would also suggest checking out this thread for some guidelines on smart posting behavior that can help you get answers that are better much more quickly.

Hi!

If you know the Beta coefficient/Standard Error/t-statistic then it is no problem because you can use the formula:
beta coeff = ""a"
Std.Err = "Sa"
t-stat = "t"

t=a/Sa ... And if you have any of these 3 variables its no problem.

But how can you calculate this when Std.Err is missing?

How about coefficient/stderr = test statistic = pvalue. A little algebra and work backward.

Hi hlsmith!

Can you please elaborate? (I know that "coefficient/stderr = test statistic = pvalue" But the stderr & test statistic is missing in this case)
I mean, how can we calculate Std.Err & t.stat when we only know that: coefficient= -9074.674 & p-value= 0.000

Best regards

Yes I see one has pvalue 0.0000. What other info do they provide in that row?

7. ## Re: Pleease help!? Filling in "blanks" in Regression Output

Try to figure out how the 95% confidence interval is found. Then you can work your way backwards.

9. ## Re: Pleease help!? Filling in "blanks" in Regression Output

Hi!
The confidence interval is found by using critical value then you can use the formula.
But I still dont see how I can work backwards using this forumula, I mean we are still missing Std.err

Come on. Lower confidence interval = estimate - (1.96 * stderr)
