    Thanks for the great video! Also, I think it's the first time I'm hearing a New-Zealander accent. So sweet!

    Awesome explanation. Loved your comment on Sampling error that it's not an error per se but the variation due to different samples :)

    Thanks for excellent explanation of confidence interval. Kindly explain, how to interpret confidence interval of Intercept.

    • @DrNic

      Generally the intercept has no sensible interpretation as it is outside the range of the data used to create the model. I think I explain that in one of the other regression videos - the first one.

    just have 1 question while considering the Age co-effcient we considersed it as for every 1 year the car gets older and when it cames to km co-efficient you considered for every 1000 km , just had a small doubt: why didnt we go with every 1km instead of every 1000km , the car travels more its price gets reduced by a certain range value, since for Age we consider as for every 1 year . may i know on what after the unit 1 or 1000 gets decided for interpreation ?

    What do you mean interval regression.thank you

    • @DrNic
      @DrNic  ปีที่แล้ว

      I'm not sure what you are asking. I do not talk about interval regression, but confidence intervals for regression coefficients.

  • @yaweli2968

    if you want to estimate the price within some confidence interval, how can you come up with the standard error for the price?

    • @DrNic
      @DrNic  2 ปีที่แล้ว

      In some computer packages you are given the standard error. It is the square root of (the sum of squares residual divided by the degrees of freedom). That would give the confidence interval for the mean of the price for those input values.

    Hi! thank you! therefore, the CI should always contain our size effects/coefficients, right?

    • @DrNic
      @DrNic  2 ปีที่แล้ว +1

      The confidence interval will always contain the statistic from the sample. However we can only be , for example, 95% confident that they contain the population parameter.
