      +Brandon Foltz , hi there nice videos ! do you have any video on how to account for confounding and effect modification in multiple regression
      analysis?

      @rishabh8960 6 лет назад

      Brandon Foltz can you please explain how do I interpret different standard errors for different regression coefficients in the multiple regression model. I understand that in simple linear model it's the average distance data falls from the regression line but there we have only one regressor variable whereas in this case exists more than on regressors so can you please explain that?

    The videos are very informative. I bet these videos contain something that no one can ever easily find inside a book. I must say "read books and do watch Brandon's videos," you'll be a master in regression analysis.

  • @pragun1993
    @pragun1993 5 лет назад +5

    Hey @Brandon Foltz ! Two doubts:
    1.) Remember in your previous videos when you laid out the formula for prediction interval and confidence interval. In case of prediction interval the formula for the interval was
    (y*)^ +t subscript(alpha/2) * (s(subscript (pred) )^2,
    where
    (s(subscript (pred) )^2 = s^2 + (s (subscript y*))^2
    s - standard error/RMSE
    s (subscript y*) - term which appears in confidence interval formula. difficult for me to expand it here, you mentioned it in CI video.
    But in this video when you were calculating PI for x=84, you multiplied directly by standard error(RMSE) of 0.3423. Isn't it wrong?
    2.) If R square = SSR/SST *100 , and SSR = SST - SSE, and Standard Error(s) = SSE/SST * 100, why in the table which is shown in the end, they don't add up to 100% for all the three variables. R sq %+ S% = 100%, right?

    At 16:44 if you want a 95% confidence interval shouldn't you use the 0.025 value since the interval is two-tailed? If you use the 0.05 value won't that result in a 90% confidence interval? Just curious if I am correct in my thinking or not! Thanks! Great videos, fyi :)
