mean deviation

n.
In a statistical distribution or a set of data, the average of the absolute values of the differences between individual numbers and their mean.

n.
Statistics. a measure of dispersion, computed by taking the arithmetic mean of the absolute values of the deviations of the functional values from some central value, usu. the mean or median.
Also called average deviation.

In the case of inflation, for every month, we calculated the absolute deviation of each analyst's forecast from the actual inflation and then averaged the results for the available data points," Chua said.
In this study, a novel adaptive speckle noise reduction algorithm using anisotropic diffusion filter based on Haar wavelet transform and the median absolute deviation was proposed.

Analysis of deviations between 0[degrees] and 24.4[degrees] without regard to positive or negative sign yielded a mean absolute deviation of 7.14[+ or -]3.95[degrees] between the anatomic axis and the horizontal axis.
Rain-rate measured by both PMCS and OTT is higher than rain-rate measured by Gauge, the relative deviations are 4.5% and 15.0%, in which absolute deviation between PMCS and Gauge is higher than that between OTT and Gauge, the possible reason is that the sampling efficiency is affected by capture probability of PMCS, and the number density of large raindrops has an unsteady step-down variance.
Three two-dimensional discrete wavelet transform features (dwt2H Mean Value, dwt2H Median Value, and dwt2H Median Absolute Deviation from the 2nd level 2D horizontal wavelet coefficient matrix) were found to sustain statistically significant differences between low CIN and high CIN cases (Table 3).

Least absolute deviation and least square method are generally used to measure the distance between two traces, and their expressions are as follows:
(b) The corresponding absolute deviation of [[??].sub.b] from the corresponding true value, normalised to the true number of signal particles, [absolute value of [[??].sub.b] - [n.sup.*.sub.b]]/ [n.sup.*.sub.s], in those ([eta], [p.sub.T]) bins that contain at least 1 signal particle.
Generally speaking, the absolute deviation [absolute value of d] rises with rising antenna condition number [kappa].
In this manuscript, we suggest a hybrid method called K important neighbors (KIN) that implements smoothly clipped absolute deviation (SCAD) regression and uses a function of the obtained coefficients as weights in construction of dissimilarity measure.
