16 1. Introduction Recall the definition of heteroskedasticity we saw last week: When the variance of Y depends on the value of X ‚ we say that there is heteroskedasticity‚ or that the error term u is heteroskedastic: Var (Yi |Xi ) = Var (ui |Xi ) = f (Xi ) = σi2 The next slide shows an example of heteroskedasticity where the variance of Y is higher for low values of X .

To state the CLT which we shall prove‚ we introduce the following notation. We assume that Xn1 ‚ . . . ‚ Xnn are independent random variables with means 0 and 2 2 respective variances σn1 ‚ . . . ‚ σnn with 2 2 2 σn1 + . . . + σnn = τn > 0 for all n. 2 Denote the sum Xn1 + . . . + Xnn by Sn and observe

wheat that was being sold to other countries went towards Stalin’s Five Year Plan to modernize the Soviet Union and to help finance his military. It was estimated that Stalin sold enough wheat to feed all of Ukraine for two years (“Stalin’s Forced Famine”). They had so much excess grain that they would even dump some into the sea or let it rot right in front of the Ukrainian people’s eyes (Perloff). The Soviet Union then closed off all borders so that nobody in Ukraine could get anything in or out

The Ukrainian Famine Genocide Background In 1922‚ Ukraine assisted in founding the USSR and joined it as the Ukrainian Soviet Socialist Republic (UkSSR). At the time‚ the leaders of the USSR became aware that the people of Ukraine greatly resented their new regime. To indirectly pacify this resentment‚ the leasers in Moscow permitted a great amount of local autonomy in the UkSSR. This was to prevent uprising and instability in their newly founded Soviet Republic. The genocide When Joseph Stalin

2013‚ marks the 81st anniversary of the most devastating event in Ukrainian history—the Holodomor‚ or the government induced famine of 1932-1933. Historian Robert Conquest uses Soviet census data to arrive at a death toll of around 5 million people throughout Ukraine and another 6.5 million deaths during dekulakisation—the elimination of landowners‚ prior to the Great Famine (Reid 116). These numbers add up to twice the number of deaths recorded during the Holocaust with a lingering possibility of
