3) root of relative square error 相对根方误差4) relative prediction mean square error 相对预测均方差 1. This paper presents criterions of relative prediction error(RPE) and relative prediction mean square error (RPMSE) on the basis of PRESS,the simple and convenient formula in the ...
‘error’ should not be confused with a ‘mistake’. error, unlike mistake, does not mean you got the wrong answer. it just means you didn’t get as close to the true value as possible. the errors in measurement are a mathematical way to show the uncertainty in the measurement. it is...
When the laser is analog modulated with the index m, the mean-root-square electrical power measured on the spectrum analyzer is –5 dBm. Since this is a sinusoid modulation, the spectral bandwidth at the modulation frequency should be much narrower than the resolution bandwidth of 3 MHz. There...
The root-mean-square-error (RMSE) of estimated by is generally less than 0.0004 and the correlation coefficient is 0.90. Based on the experiential formula between and , surface can be computed with combination of auxiliary data such as DEM and air temperature (a). The mean absolute errors of...
Hello, Does anyone know why we use the root mean square of the relative velocity in calculating the mean free path? As is done in this example: http://galileo.phys.virginia.edu/classes/152.mf1i.spring02/MolecularCollisions.htm Seems like it would make more sense to find the mean of the...

According to the formula of sample size, the sample size should be 641(641 = 1.96 × 1.96 × 0.184 × (1–0.184)/0.03/0.03), however, the 5% of sample size needed to be increased for sampling error. Therefore, the minimum sample size was 673 (673 = 641 ...
Transpirational water loss was determined by weighing pots at seven time points throughout the day under the prevailing temperature and RH % conditions, when VPD increased through the time course of the day. VPD was calculated from these temperature and relative humidity % data using the formula:...
