Thus, the coefficient of x103 is:20∑k=0(199k)(−1)k(301−5k198) Step 6: Evaluate the sumWe can evaluate this sum. However, upon further inspection, we find that for k=20, m becomes negative, and for k=19, m is 8, and so forth. After evaluating all possible values, we...
Estimate parameters β1 and β2 of the regression straight line E(y / x) = β1x + β2 with the use of (a) the classical LS method, (b) the generalized LS method for the case of cumulative errors, and (c) the generalized LS method for the AR(1) model of errors. ◯ Data: ...
Sample correlation coefficient of $X$ and $Y$ is determined by the formula $$\begin{align} r_{XY}&=\frac{1}{n-1}\sum_{i=1}^n\frac{(x_i-\bar{X})(y_i-\bar{Y})}{s_Xs_Y}\\\ &=\frac{\sum_{i=1}^n(x_i-\bar{X})(y_i-\bar{Y})}{\sum_{i=1}^n(x_i-\bar...
最近实验发现来自宇宙的超高能(E_r>10~(15)eV)r-线有两方面特别重要:(1)已与十多个高能天体相对应(见Nature,315(1985),205),其中银河系内7个:CygX-3、VelaX-1、CirX-1、ScoX-1、CenX-3、GX301-2、GX304-1,大麦哲仑云中4个和小麦哲仑云中1个, E_r=(4—15)×10~(15)eV,流强F_r=(...
In this paper, numerical solutions of the variable-coefficient Korteweg-De Vries (vcKdV) equation with space described by the Caputo fractional derivative operator is developed. The propagation and interaction of vcKdV equation in different cases, such a

CONSTITUTION:A signal X(n) supplied to an input terminal 100 is delayed by a delaying circuit 101 and becomes a signal of X(n-i), also, when an output signal of a coefficient generating circuit 501 is denoted as ri(n), an output signal of an adder 301 becomes X(n)-ri(n).X(n-...
The STVC showed better performance in handling spatial dependence of corn production, which tends to cluster estimation residuals when counties are close, with the lowest Moran's I of 0.10. Considering the spatiotemporal non-stationarity, the proposed model significantly improves the power of the ...
