Statistical explanations and the 2nd Presidential Debate After the 2nd presidential debate, I was watching the MSNBC discussion and Al Sharpton made the point that the area had a lot of African Americans but only one African American was there to ask questions. Earlier this campaign cycle Mitt Romney in one poll scored a 0 with African Americans. In a poll they found absolutely no African Americans who supported Romney. Its quite rare. But, also very relevant. The makeup of the audience of the town hall there is "undecided" voters, who are uncommitted and from the local area. Thats a massive bias in the numbers. That demographic isnt the wishy-washy with support. Hence the appearance of white-washing. download  file  now

STATISTICAL ANALYSIS USING RANDOM SETTINGS IN NS2 While running ns2, we always get the same results as much we run with the same parameters. If we need to get different results for running with same parameters,we need to add some random property in our scripting. By using this property, we can check what goes wrong at an exact point. Normally in ns2, simulations are under three categories; DETERMINISTIC SETTING This setting is the default setting of ns2 and we get the same output in every run. This simulation scenario is usually convenient for debugging process and to locate errors that occurred in simulation codes or to study about complex nature of networks. So while running in deterministic setting, we will get same results on every time and which helps easy to analysis. RANDOM SETTING In case of a statistical analysis, we are forced to simulate a simulation scenario several times and to find out mean & variance. By using deterministic setting we are not able to do this because ...
