The errorFunction(x/(sd * Math.sqrt(2)))
is the probability that a value in a
normal distribution with standard deviation sd is within x of the mean.
This function returns a numerical approximation to the exact value. It uses Horner's method to evaluate the polynomial of τ (tau).
Examples
errorFunction(1).toFixed(2); // => '0.84'
errorFunction(1).toFixed(2); // => '0.84'
