Economics questions
Generate a covariate matrix X of dimension n × k, where n = 250 and k = 4. The fifirst column in X should
be a column of ones and the other three columns can be generated from a relatively diffffuse normal or
uniform distribution.
Let β = (0.5, 0.75, 1, 1.25)0 and let σ2 = 1. Simulate y from the model y = Xβ + ε, where ε ∼ N(0, σ2In).
Estimate β by ordinary least squares and report βˆ OLS and the standard errors in a table. [Hint: the
standard errors are computed by taking the square root of the main diagonal of s2(X0X) 1 , where s2 is
computed as discussed in class.] Also submit your computer code (this should not take more than 20 lines)

The Life of Donald Trump GuidesorSubmit my paper for investigation You may know him as the 45th President of the United States of America, or an unscripted tv star. Others may allude to him as a moron, narcissist, and awful individual—these are altogether features of his character. In any case, so as to maintain a strategic distance from inclination and political tirades, we will investigate an incredible realities. Despite the fact that there might be a riddle blurring the exercises at the White House, there are very few figments about the sort of life Trump has driven. His youth was for all intents and purposes effortless. He was conceived on June 14, 1946 into a well off family, as the fourth offspring of conspicuous New York land designer Fred Trump, and housewife Mary Trump (BBC News). His grandparents on the two sides of his family were migrants—his dad’s side originated from Germany, and his family members from his mom’s side originated from Scotland (Kranish, Michael, and Marc Fisher). He was brought up in Queens, New York, and went to the Kew-Forest School from kindergarten until the seventh grade. At 13 years old, he was sent to the New York Military Academy, a private live-in school, as his folks needed to clean his character (Kranish, Michael, and Marc Fisher). In the wake of moving on from secondary school, Trump went to Fordham University in 1964, and two years after, he moved to the Wharton School of the University of Pennsylvania (Blair, Gwenda). During his time at Wharton, he worked at his privately-owned company, and graduated on time in 1968 with a Bachelor’s of Science qualification in financial aspects (University of Pennsylvania). Around the same time, Trump began working all day at the family organization, E. Trump and Son. The organization concentrated on possessing working class rentals in New York City. Supporting his dad for a long time in reviving certain edifices, senior Trump became administrator, and junior Trump turned into the leader of the organization. At the point when this change occurred, Donald renamed the organization “The Trump Organization” (Blair, Gwenda). The focal point of the organization on external wards of New York City stopped in 1978 when The Trump Organization bought a 50-percent stake in the Commodore Hotel. By 1980, the inn was revived as the Grand Hyatt Hotel (Wooten, Sara McIntosh). Additionally, in 1980, Trump reached skyward again by building a high rise in Midtown Manhattan by the name of “Trump Tower” (The New York Times). From this time, there appeared to be no thinking back for his domain vocation: he made or procured the Wollman Rink in Central Park (1980), the Mar-a-Lago bequest (1985), the Plaza Hotel (1988), the Trump International Hotel and Tower (1994), Trump Building (1996), Trump Place (1997), the Trump World Tower (2001), and Trump Park Avenue (2004). Moreover, The Trump association claimed as well as constructed different fairways, club, brands, sports groups, Miss Universe shows, the Trump University, and the Donald J. Trump Foundation (Tigas, Mike, et al). However, with this achievement, Trump petitioned for financial protection multiple times (Fiorina, Carly), and got hitched multiple times (Avella, Joe). He presently has five kids, with three children, and two little girls. Notwithstanding this exciting ride of achievement and disappointment, Trump’s name got synonymous with “very rich person” and “reckless” through his hit network show “The Apprentice” that started to air in 2004. Trump was its host and judge for 14 seasons, and during this timespan, Trump turned into an easily recognized name (The Washington Post). This developing achievement, by most records, made his run as a Republican presidential competitor in 2016 triumphant. In spite of the fact that the truth star and business head honcho was a far-fetched decision for being the 45th leader of the United States, most of political specialists accept he won the political decision because of Hillary Clinton being an ominous contradicting competitor, his all day, every day media consideration, and his character seen as not quite the same as the typical legislative issues (Zurcher, Anthony). Despite the fact that he ran a wild, outrage ridden, and flighty battle, he won the appointive decision in favor of being president, and is as of now discussing re-appointment. Donald Trump may be the most discussed individual on the planet at that point, notwithstanding his presidential success being just about two years prior. Naturally introduced to a rich family, he was brought up in a way that would befit him as the following leader of his dad’s land organization. In the wake of acquiring a four year college education, he immediately got immersed in working all day for his dad organization, and moved the focal point of the association to huge structures instead of white collar class rentals. From this choice, he has assembled a ground-breaking brand that was just fortified through his long spell as an unscripted tv star. Through this critical picture, he was shot into the political field, and effectively ran as a presidential up-and-comer, turning into the 45th President of the United States.
