Econometric Project on Diamonds

Sacha Froelich ECO 4421.001 Project Diamond December 2, 2011 Research Questions: When viewing diamonds, how is toll primed(p)? The typical response is the 4 Cs (carat, color, clarity, and cut). I want to collar how accurate and important the carat, color, and clarity argon in determining price. Ideally, I wanted to flummox into bring in the reliability of different Gemmological grading but as I couldnt find entropy that allowed for direct similarity utilise the same group of diamonds, I had to go with this circumscribed prodigy of diamond prices instead. Dataset Description: N = 180 observations Y = terms, in dollars X1 = karat, weight/size of a diamond with 1 Carat = 0.2 grams; my range being 0.5 to 1.01 Carats X2 = Color, which will be however abject down into: D=1, E=2, F=3, G=4, H=5, and I=6 X3 = Clarity, again broken into: 1IF=18, 2VVS1=19, 3VVS2=21, 4VS1=22, and 5VS2=23 (these values were railroad car generated by STATA as 1-6 were already taken ( Im crack from my Clarity) it in the first place gave me 7-11 but as I had to tweak the articulate in which they appeared because it kept victorious it alphabetically which threw off my scale, thitherfrom the 1IF vs.

IF each new batch gave a numerical subsidisation that went further down the pike which is how I/STATA arrived at the poem given) The data was used as grapheme of Statistix 9.0 software when I took Stats II in Spring of 2011 and originally was published in Singapores Business clock edition on February 18, 2000. I have taken a portion of it here for my use. I attempted to find much current data but couldnt locate anything that was fr! ee. square up: http://www.amstat.org/publications/jse/jse_data_archive.htm My stupefy: I would assume that the Multiple Linear statistical regression (MLR) would be the best model. I do propose that Price is hooklike upon the Carat size, Color, and Clarity. I do expect to see a strong positive relationship between these variables and the price. Although, I do believe that Cut is also a deciding factor, it wint...If you want to get a full essay, baffle it on our website: OrderCustomPaper.com
