Error percentage

All values were calculated for intrinsic viscosity of gelatin B solutions to 37.4°C and compared against the value of Huggins, normally used as standard. It is noteworthy that each method has a relative error percentage and low for methods of more than four pair s values (Er% > 0.30). [Pg.91]

The slopes and linear coefficients of lines allow to determine the Ng and values corresponding to these runs these values are almost the same as those determined by means of Equation (19) (error percentage, +4%). Eigure 8 also reports the adsorption results obtained in the absence of irradiation, that is, in the dark. A least-squares best fitting procedure allows to determine the values (R > 0.99) of the Langmuir equilibrium constant and the maximum adsorption capacity in the absence of irradiation, that is, fCL = 350 and Ns = 4.57 x 10 mol/g of catalyst. [Pg.23]

Water and Aqueous Solutions. The high permittivity and high relaxation frequency of water presents a formidable challenge to t.d.s. methods, as virtually all error percentages increase as sample permittivity and measuring frequency increase. At the same time, it is in the microwave region... [Pg.66]

The NMR results are certainly more accurate than any other chemical method. There are no side-reactions and there is no interference with other reactive functions as is observed in chemical analysis1,83. When a good signal-to-noise ratio is obtained the precision (relative error percentage) is 5%. For the chemical analysis of hydroxyl the relative error is 5-15%. A single NMR spectrum can yield information concerning a very complex silicone fluid that would otherwise require several different analytical methods. [Pg.1309]

The accuracy of an individual value or of an average experimental value can be compared quantitatively with the correct or accepted value by calculating the percentage error. Percentage error is calcuiated by subtracting Ihe accepted vaiue from the experimentai vaiue, dividing the difference by the accepted vaiue, and then muitiplying by 100. [Pg.44]

The error value used in this study to evaluate training, validation and testing was the squared error percentage (E see Prechelt, 1994), with corrections (Clark, 2000,2003), given in Equation 12.1 ... [Pg.212]

This is also demonstrated in Fig. 23.19, where the approximation function according to (23.12) was drawn as a line calculated with the approximation parameters n = —0.169 and m = 0.08 fitting the mean and the maximum secondary drop diameter ( 50,3 and dependencies. The average relative error percentage for the deviations of the experimental data from the approximation functions were 9 % and 10 % for X5o,3/x5o,3,initiai and X9o,3/x9o,3,initiai, respectively. [Pg.972]

Clearly, the HF method, independent of basis, systematically underestimates the bond lengdis over a broad percentage range. The CISD method is neither systematic nor narrowly distributed in its errors, but the MP2 and MP4 (but not MP3) methods are reasonably accurate and have narrow error distributions if valence TZ or QZ bases are used. The CCSD(T), but not the CCSD, method can be quite reliable if valence TZ or QZ bases are used. [Pg.2191]

Percentage error for LN compared to reference Langevin trajectories (at 0.5 fs) for energy means and associated variances for BPTI over 60 ps at 7 = 20 ps At = 0.5 fs, Atm = 3 fe, and At — k2Atm, where hz ranges from 1 for LN 1 to 96 for LN 96. Table 2.

But decision making in the real world isn t that simple. Statistical decisions are not absolute. No matter which choice we make, there is a probability of being wrong. The converse probability, that we are right, is called the confidence level. If the probability for error is expressed as a percentage, 100 — (% probability for error) = % confidence level. [Pg.17]

Using your optimized expression for W, calculate the estimated total energy of each of these atoms and ions. Also calculate the percent error in your estimate for each ion. What physical reason explains the decrease in percentage error as Z increases ... [Pg.87]

The distribution of the /-statistic (x — /ji)s is symmetrical about zero and is a function of the degrees of freedom. Limits assigned to the distance on either side of /x are called confidence limits. The percentage probability that /x lies within this interval is called the confidence level. The level of significance or error probability (100 — confidence level or 100 — a) is the percent probability that /X will lie outside the confidence interval, and represents the chances of being incorrect in stating that /X lies within the confidence interval. Values of t are in Table 2.27 for any desired degrees of freedom and various confidence levels. [Pg.198]

Accuracies of the flow meters discussed herein are specified as either a percentage of the full-scale flow or as a percentage of the actual flow rate. It may be convenient in some appHcations to compare the potential inaccuracies in actual volumetric flow rates. For example, in reading two Hters per minute (LPM) on a flow meter rated for five LPM, the maximum error for a 1% of full-scale accuracy specification would be 0.01 x 5 = 0.05 LPM. If another flow meter of similar range, but having 1% of actual flow rate specification, were used, the maximum error would be 0.01 x 2 = 0.02 LPM. To minimize errors, meters having full-scale accuracy specifications are normally not used at the lower end of their range. Whenever possible, performance parameters should be assessed for the expected installation conditions, not the reference conditions that are the basis of nominal product performance specifications. [Pg.56]

The percentage error in the temperature difference translates directly to the percentage error in the estimate Q. As temperature-measurement error increases, so does the heat transfer coefficient error. [Pg.2556]

Equation (1). the fuel gas equation, does not hold for unsaturated hydrocarbons, but for small percentages of unsaturates the error is not serious. [Pg.335]
