10 Generalized Linear Regression In the problems of this section $x^T \beta = \beta_0 + \sum_{i=1}^p \beta_i x_i$ Problem 10.1. $\epsilon \sim \text{Logistic}(0, 1)$, if its probability density function (pdf) is $\sigma'(x) = \frac{d}{dx}\sigma(x) = \frac{e^{-x}}{(1 + e^{-x})^2}$ a) Verify the primitive function $\int \sigma'(t)dt = \frac{1}{1 + e^{-x}} + C$ and determine C. Set $\sigma(x) := \frac{1}{1 + e^{-x}}$. b) Show that $P(-\epsilon \le x) = P(\epsilon \le x)$. You may use (131) even if you have failed to show it. c) Define $Y^* = x^T \beta + \epsilon$ and construct $Y = \begin{cases} 1 & \text{if } Y^* > 0\\ 0 & \text{otherwise.} \end{cases}$ Verify that $P(Y = 1 | x) = \sigma(x^T \beta)$. You may use (132) even if you have failed to show it. (133) d) The r.v. Y in this assignment is a special case of generalized linear regression (GLM). The way to construct a GLM goes via a link function. Present and justify the link function in this assignment.

Under the gold standard, gold flows reduce the money supply in one nation when another nation experiences a trade surplus. The nation with a trade surplus has a swell in the money supply, which leads to price increases. At the same time, the nation with a reduction in the money supply will cause prices to fall. The lower prices create more demand for product from the nation with a reduction in the money supply, which leads to a Ofloating exchange rate. Otragedy of the commons. Obalance-of-trade. Ofacilitating payment. O planned economy.

1. Build a VI that generates a 2D array of three rows and ten columns and contains random numbers between 0 and 1. Can you now change this so that random numbers are between 0 and 100 and finally change it to lie between -50 and +50? 2. Use the above VI to create a waveform graph and plot the data on a single graph.
