    SMITHA TOM

      I wanted to create Q-Q plot and this is the formula i used in Tableau. Could some one please tell me how is this formula created.

       

       

      5.6865*10^-11*(-14.17234*LN(1/RANK_PERCENTILE(AVG([Life exp (years)]))-1))^5

      -1.6795*10^-6*(-14.17234*LN(1/RANK_PERCENTILE(AVG([Life exp (years)]))-1))^3

      +0.042192*(-14.17234*LN(1/RANK_PERCENTILE(AVG([Life exp (years)]))-1))
