    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.

  • @anneiza8953
    @anneiza8953 6 лет назад

    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.

  • @prachigupta9060
    @prachigupta9060 6 лет назад

    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 5 лет назад

      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 5 лет назад

      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

    calculate critical and" f " statistic value considering the following information :
    Significance level 0.05
    Numerator 11.
    denominator 3.
    Total sum of Square 160.
    Treatment sum of square 60.
    Observation number 25.
    treatment number 5.
    By solving this someone help me.
