Logarithmic Linear Regression

This is not an issue of log versus non-log. You should sort your
xdata before plotting the line; you just don't notice it when you plot
nonsorted data that all lie on the same line.

Just do this after your data definition


Also, rather than

  x = [f[0] for f in prediction_experiment]
  y = [z[1] for z in prediction_experiment]
  x = array(x)
  y = array(y)

you might prefer

  x, y = map(array, zip(*prediction_experiment))
