    GREAT, CLEAR , CONCISE, COHERENT explanation. The speed of the deliverance was a bit intimidating, like Tennis ball thrown from a pitching machine. I played the video at .75 speed and it became even enjoyable. Above all your lesson is SPOT ON helpful.

    i like how you used an easy to digest small dataset

    How do you define s or s^2.

      Exactly my question as well.

      S² is the mean square error....its the sum of the square of the difference in the known values of y and predicted values of y divided by the no of variable pairs all square rooted
      s²=sqrt((Σ(yᵢ-ŷ)²/(n))

      you'll use the regression line to get the predicted values of y

    Hi Katie, I hope you do not mind me asking, but after watching dozens of videos, it seems that you are the only person who can help me. I am performing Total Least Squares / Orthogonal Distance regression with a non-linear model Ln(P) = a + b / (T + c), where a, b, and c are the adjustable parameters. I am also treating the function as an implicit function F = Ln(P) - a - b / (T+c) =0. After convergence, how do I calculate the Standard Error (SE) for each of the adjustable parameters ? And, can you please say something about K (or Kappa?) ? In the mean time, I'll add subroutines to calculate the averages for T and P, t-distribution, etc. I Really hope to hear from you. A link to a CLEAR paper will suffice.

      k, means a numbe of independent variables in the equation, the equation is simple linear regression and there is only one value of x
