<p>Note: Experience has shown that a factor between 3 and 5 to scale sigma is a good
-discriminator to detect abnormal behaviour. This obviously depends also on the type
+discriminator to detect abnormal behavior. This obviously depends also on the type
of data and how "noisy" the data series is.</p>
<p>This prediction can only be used for short term extrapolations - say a few days into the future-</p>
</dd>
<dd>
<p>Returns the rate from each defined time slot multiplied with the
-step size. This can, for instance, return total bytes transfered
+step size. This can, for instance, return total bytes transferred
when you have logged bytes per second. The time component returns
the number of seconds.</p>
