SSSS— Sum of squares; yiyi— The ith value in the sample; yˉyˉ— Mean value of the sample; and yi−yˉyi−yˉ— Deviation of each data point from the mean. To better understand the formula, let's discuss an example. Suppose you're trying to calculate the sum of squared devi...
explain the variation in the dependent variable. Therefore, the ESS is a useful measure for comparing models. However, the ESS is not the only measure to consider when comparing models. Other measures, such as the residual sum of squares (RSS) and the adjusted R-squared can also be helpful...
Find a pointAon thexy−plane such that the sum of squares of distances betweenAand linesx=0,y=0,andx+2y−16=0is minimal. Distance: In mathematics, physics distance is the numerical measurement between two points that how far t...

The residual vector is defined as the difference between the measurement and the estimated valuesr=z−h(x)and it is weighted by the inverse of the error standard deviationσ. Therefore, the WLS estimator Eq.(2)is an optimization problem, which minimizes theweighted sumof the squared residual...
are found, the final refinement of the motion estimation process is often done with other slower but more accurate metrics, which better take into accounthuman perception. These include thesum of absolute transformed differences(SATD), thesum of squared differences(SSD), andrate-distortion ...
,k}); and the norm x-y2designates the squared Euclidean distance between the two points x∈Rd and y∈Rd, i.e., x-y2=∑r=1d(xr-yr)2. MSSC is known to be NP-hard [8]. Accordingly, the problem is computationally challenging. To practically solve MSSC, a variety of heuristic and...
