    superb! I wish you were my teacher back in school. i have nothing to do with statistics now but still I have come this far, to 4th part of your video, because of your explanation. They just kept me interested. Awesome! Please keep making such videos.
    Believe me, not many students understand stats and not many teachers know how to teach stats. The way you teach is absolutely good and practically understandable. Thank you so much!

      Hey! How do you convert percentage into binary output?

    • @alxndrdg8
      @alxndrdg8 2 года назад +2

      @@ammar46 step-1: first have the percentage ready in decimal format (e.g. 45.8%)
      step-2: if you are using any programming language it will have a built-in function to convert decimal no. to binary no.
      step-3: if you are writing a function yourself you need to understand how the left part of decimal is converted to binary and how the right part of decimal is converted to binary.
      You can find this converstion math in any computer logic text book or video. Write your function accordingly.

    Hi, at the time 11:14 , you mentioned, for a $1000 increase in price, the odds of selling a car decreases by 16%, while exp(-0.1730) is 0.84 which is 84%. Could you please explain

    • @zedstatistics
      @zedstatistics  4 года назад +24

      84% actually means a 16% reduction! If my weight this year is 84% of my weight last year, then I have achieved a 16% weight reduction (100%-84%). Hope that helps

    • @abdouljabbar4656
      @abdouljabbar4656 3 года назад +1

      Maybe a mathematically more intuitive explanation
      Ln (p/1-p)= 0.396-0.173 (price)+1.555 (PS), then (p/1-p)= e^(0.396-0.173[price]+1.555[PS]) which can be rewrite p/1-p= e^0.396 x e^-173 (price) x e^1.555 (PS), hence the multiplicative effect of e^-173 or 0.84 on the odd of selling the car (p/1-p) with 1 extra unit of the price. Since this model is already presented in the context of post-hypothesis testing (remember the coefficient for the price in the model has a p value

    @zedstatistics At 17:31 you have shown how to did we come across the value 4.73 for pink slip. How do we derive the value 0.84 for price variable as in case of pink slip we calculated for scenarios with pink slip and without pink slip. How doe we do the same in case of price?

    • @sjaun1514
      @sjaun1514 2 года назад

      You just need to reverse the process shown above so keep the Pink Slip as a constant value of 1 (or 0 if you prefer) and adjust price to 1 [i.e. 0.396+(-0.173*1)+(1.55*1)] for the first calculation and 0 for the second i.e. [0.396+(-0.173*0)+(1.55*1)] (so just reversing what he showed when calculating 4.73)

      @ssandok 3 года назад +5

      The line about it has (P+3.23P) on the left side. Factor out the "P" and you have P(1+3.23). So that's 4.23P on the left side. Then you're wanting to get P by itself, so divide by 4.23.
