Multiplicative absolute error

This plot captures the multiple steady state part. However, to predict the effectiveness factor at higher values of O, we choose initial values ranging from le - 40 to le - 10. For these low values, one has to perform highly accurate simulations. For this purpose, absolute error (abserr) is set to le - 41 and the relative error (relerr) is set to le - 12. 

The real zirconia gas sensor fnnction is located between two dotted lines due to the inconsistency of both sensitivity and the initial level of output signal of the sensor. The uncertainty of measurements is restricted by the value 2Aq + where A() is the absolute error of the zero level, or additive absolute error is the absolute sensitivity error, or multiplicative absolute error and is the relative sensitivity error, or relative multiphcative error. 

B-VWN and B-LYP, on the other hand, perform very well and give binding energies with very small mean error. For B-LYP, the mean error is 1.0 kcal/mol and the mean absolute error is 5.6 kcal/mol. The molecules which are underbound at this theoretical level are the simple hydrides with lone-pair electrons (H2O and NH3, for example). On the other hand, molecules with multiple bonds, as well as H2O2 and F2, tend to be overbound. The low mean error is partially due to the fairly small basis set used B-LYP theory leads to some overbinding with a large basis. 

Fig. 7.13 We consider the stability of a multiple timestepping scheme incorporating Langevin dynamics, with potential energy function (7.47) choosing 12 = 3. Each pixel represents a simulation undertaken with parameters (t, y), for t = Qh. The color of a pixel indicating the absolute error in (q )f where white pixels indicate instability of the method. The plotted line gives the boundary to the region in parameter space where (7.49) is satisfied...

Majumdar et al. [24] used the multiple regression model to predict tensile strength of plain woven fabric and found that correlation coefficient between actual and predicted value are 0.811 with 13.65% absolute error of prediction. They used five input parameters namely warp yam strength, warp yam elongation, EPI, PPI, weft count for the predietion. Apart from warp yam strength and ends per inch, weft count is also dominant parameter affeeting tensile strength of woven fabrie. 

Because a FIXE spectrum represents the int al of all the X rays created along the particle s path, a single FIXE measurement does not provide any depth profile information. All attempts to obtain general depth profiles using FIXE have involved multiple measurements that varied either the beam energy or the angle between the beam and the target, and have compared the results to those calculated for assumed elemental distributions. Frofiles measured in a few special cases surest that the depth resolution by nondestructive FIXE is only about 100 nm and that the absolute concentration values can have errors of 10-50%.

First, there is the obvious objection that there may be no experimental values for the properties and systems of interest. Second (and almost as obvious) is the possibility that the experimental values are wrong. Third, the experimental values may in fact be derived from experimental measurements by a number of steps that involve assumptions or other theoretical calculations. All of these objections are important, but in one sense they are orthogonal to the real issue what if our calculations contain multiple sources of error that can cancel with one another We know already that any truncated one-particle space and truncated jV-particle space treatment has two sources of error, these two truncations. And there is no reason to suppose that the error from these two sources cannot cancel, indeed, from the early days of large-scale correlated atomic wave functions there is good evidence that they do cancel [35]. Hence even if there are absolutely reliable experimental values for the properties and molecules we want to consider, using them to calibrate theoretical methods may be useless unless we can establish whether we have a cancellation of errors or not. 

The genetic code invariance persuaded evolutionists to throw the first shy proponents of polyphyletic models into the dungeons.17, 18 The contention that chance would not have provided even for two origins with an identical triplet codon for protein synthesis was then and still is absolutely correct and certainly relevant, but the conclusion reached because of it by nearly everyone was not. Multiple origins were declared impossible whereas chance should have been disqualified as an inappropriate term in this equation (which it is), and this was the error that has dominated thinking for more than 150 years and is still defended with vehemence. 

Most pressure sensors detect the difference between the measured value and a reference. In the case of absolute pressure sensors, the reference chamber cannot be evacuated to absolute zero, because it can only be approached within a few thousands of a millimeter of mercury (torr). In the case of positive pressure detectors, when the barometric pressure is the reference, atmospheric pressure variations can cause errors up to 25 mmHg. Intelligent transmitters can also operate with multiple references and switch them as required. 

The estimation of the error of a computed result R from the errors of the component terms or factors A, B, and C depends on whether the errors are determinate or random. The propagation of errors in computations is summarized in Table 26-2. The absolute determinate error e or the variance V = s for a random error is transmitted in addition or subtraction. (Note that the variance is additive for both a sum and a difference.) On the other hand, the relative determinate error ejx or square of the relative standard deviation (sJxY is additive in multiplication. The general case R = f A,. ) is valid only if A, B,C,... are independently variable it is... 

If only the multiplicative constituent part is present, then the function of the zirconia gas sensor assumes y = fc(l y ) x, where y = Yt is the current value of the relative error. In this case, the function of the measuring parameter of the sensor is the absolute value of the error.
