The instrument measured the vertical water vapour profile, with less than 10 per cent

mean error over a range of atmospheric conditions, as compared to profiles collected by airborne devices.

Thereby, it is possible to extract some values very useful for choosing the method, such as the

mean error (ME), the standard deviation of

mean errors (S[D.sub.ME]), the reduced

mean error (RE), and the standard deviation of reduced

mean errors (S[D.sub.RE]).

Lower

mean error rates were seen for surgeons' SR notes versus those of other physicians (6.0 versus 8.1 percent).

Adjusting the old price by the average price change produces the smallest

mean error, -$2.

The percentage of

mean error for prediction of [C.sub.p] by various models and their standard deviation is shown in Figure 11.

A maximum

mean error of 0.334 mm (SD = 0.257 mm) for experiment four is shown.

Figure 8 shows a box plot of position errors of 3-day forecasts for TCs over the globe from 2012 to 2014 and the

mean error of each NWP center.

The maximum and minimum measurement errors rates are 5.358 percent and 0.001 percent, respectively with

mean error measurement of 1.717%.

7 it could be noted that the absolute value of the

mean error is at least 5 times smaller than the value of standard deviation for a given modulation index.
