    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?
    Please help me, thank you!
    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)
