3 -0.751 (X1,X2, X3) be jointly Gaussian with ux (1,-2,3) and Cx 1. Let X = 3 0.25 4 L-0.75 0.25 Hint: If a set of random variables (RVs) are jointly Gaussian, then any subset of those RVs are also jointly Gaussian. Similarly, adding constants to (or taking linear combinations of) jointly Gaussian RVs results in jointly Gaussian RVs. Using this property you can solve problem 1 without using integration. When appropriate, you may express your answer by saying that...
solvel only E F G H below is pat data 3. A hospital administrator wished to study the relation between patient satisfaction (Y) and patients age (Xi, in years), severity of illness (X2, an index) and anxiety level (X3, an index). The administrator randomly selected 23 patients and collected the data in pat, where larger values of Y, X2 and X3 are, respectively, associated with more satisfaction, increased severity of illness and more anxiety. The data is saved in Moodle2...
Problem 3 (Some parts borrowed from Mitra, Ch.4). The cross-correlation function ray(t) between two real-valued CT signals r(t) and y(t) is given by We use the cross-correlation to detect whether two signals are related to each other by delay. The autocor- relation function rt) of a real-valued CT signal r(t) is given by One use of the autocorrelation function is to detect the period of the signal. 1. Find the autocorrelation of z(t)-e-at u(t) for α > 0. 2. Find...

The following problem is based on the idea of a Malthusian trap. Thomas Malthus, an 18th century British cleric and scholar, argued that as population increases, the limited amount of natural resources will lead societies into a trap of gradually decreasing standard of living, thus negating the effects of any technological progress. We can study this idea using the Solow model framework. Consider a modified version of the Solow growth model where the aggregate production function in period t is...
