In forecasting a monthly time series over a five-year period from January 2006 to December 2010, the exponential trend forecasting equation for January is shown below. $\log (Y_i) = 1.9 + 0.01X_i + 0.10(\text{January})$ Take the antilog of the appropriate coefficient from this equation and complete (a) through (c). a. Interpret the Y intercept, $\hat{\beta}_0$. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. (Round to two decimal places as needed.) A. The Y intercept, $\hat{\beta}_0 = \text{_____}$, is the fitted value for January 2006 after adjustment with the January multiplier. B. The Y intercept, $\hat{\beta}_0 = \text{_____}$, is the fitted value for January 2006 prior to adjustment with the January multiplier. C. The Y intercept has no interpretation in this context.

Derive the normalized LMS whose objective is to minimize the change of the weight vector $||\delta w(n+1)\||$ subject to the constraint that $\mathbf{u}^H(n)\mathbf{w}(n+1) = d(n)$. Here, the filter input is $\mathbf{u}^H(n) = [u(n), u(n-1), \dots, u(n-M+1)]$ and $u(n)$ represents the observation at time $n$.

Question Define R as the region that is bounded by the graph of the function $f(x) = \sqrt{3} \sin(x)$, the $x$-axis, $x = \frac{\pi}{4}$, and $x = \pi$. Use the disk method to find the volume of the solid of revolution when R is rotated around the $x$-axis. Submit an exact answer in terms of $\pi$.

2. The filter parameter of a real AR(1) process embedded in white noise of variance $\sigma_w^2$ is estimated using $\hat{a}[1] = -\frac{r_{yy}[1]}{r_{yy}[0]}$ where $y[n]$ denotes the noise corrupted process. Show that $\hat{a}[1] = a[1]\frac{\eta}{\eta + 1}$ where $\eta = r_{xx}[0]/\sigma_w^2$ is the SNR. Generalize the result to a real AR(p) process in white noise to show that $\hat{\boldsymbol{a}} = (\boldsymbol{R}_{xx} + \sigma_w^2\boldsymbol{I})^{-1}\boldsymbol{R}_{xx}\boldsymbol{a}$ where $\boldsymbol{a}$ and $\hat{\boldsymbol{a}}$ are the true and estimated AR parameter vectors and $\boldsymbol{R}_{xx}$ is the autocorrelation matrix.
