Curve fitting

with 3 comments

From a study published in Science1,

The dashed line is a quadratic polynomial (given by y = -0.516 + 1.08x - 0.23x^2) which gave the best fit to the points.

Can you spot the duck?

  1. Hehe, nice find. I’m slightly skeptical, though. I couldn’t access the paper, and Harrison’s page just gives a very brief summary. It’s quite unbelievable that Science could publish this (as late as 1978!), perhaps there were not trying fit a curve ? It looks like something of a weighted histogram to me..

  2. Harrison says that the caption to the figure in the published article read,

    “The dashed line is a quadratic polynomial (given by y = -0.516 + 1.08x - 0.23x^2) which gave the best fit to the points.”

    You’re right, I’ll have to check and see If I can find this particular article in the library.
