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!

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?

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

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)
