    Hello, your video is very useful. I have a doubt when 0 or value less than cero appears in the confidence interval, You mention that there is no linear relationship between x and y values. If this happens can a quadratic or cubic model be given? or what could be the model?
    Please, woul you explain me.
    Thanks.

    Very good, so what if one of the coefficients fail the test? Do you have to redo the model without that variable then?

  • @morganyakkov5804
    @morganyakkov5804 Před 3 lety

    I think there is small mistake on the slide. SSE(yellow) is actually distance from the actual point to regression line, and SSR(green) is supposed to be from mean line to regression line.

  • @prachigupta9060
    @prachigupta9060 Před 6 lety

    correct me if I'm wrong but I'm a bit confused here. Doesn't the rule say that if the t-statistic or the calculated value is more than the critical value, we reject the null hypothesis? Then how are we passing the test here?
    According to the curve, the t value should lie between -2.228

    • @shannykse7110
      @shannykse7110 Před 5 lety

      yes we reject the null hypothesis.. meaning we pass the alternative hypothesis.. he was referring to the alternative test when he said pass/fail.

    • @diaconescutiberiu7535
      @diaconescutiberiu7535 Před 5 lety

      Null hypothesis means "m" is = 0 so y would become y=b which means x is not related to y. We don't want that...it would mean no relationship between x and y, thus we reject this and accept alternative... meaning m different from zero...thus there is a relationship between y and x...that would be y =mx+b

    a) the slope of a line
    b) the intercept of a line
    c) the coefficient of determination
    d) the coefficient of correlation
    e) both C and D are correct
