Econometric Project on Diamonds

Sacha Froelich ECO 4421.001 Project Diamond December 2, 2011 Research Questions: When viewing diamonds, how is wrong primed(p)? The typical response is the 4 Cs (carat, color, clarity, and cut). I want to watch out how accurate and important the carat, color, and clarity are in determining price. Ideally, I wanted to transmit into bring in the reliability of different Gemmological grading but as I couldnt find entropy that allowed for direct similitude utilise the same group of diamonds, I had to go with this circumscribed prodigy of diamond prices instead. Dataset Description: N = 180 observations Y = legal injury, 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 nevertheless 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 originally gave me 7-11 but as I had to tweak the articulate in which they appeared because it kept taking 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 interrupt of Statistix 9.0 software when I took Stats II in Spring of 2011 and originally was published in Singapores Business quantify edition on February 18, 2000. I have taken a portion of it here for my use. I attempted to find more(prenominal) current data but couldnt locate anything that was free. get ho ld: http://www.amstat.org/publications/jse/j! se_data_archive.htm My stupefy: I would assume that the Multiple Linear obsession (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 decision making factor, it wint...If you want to get a full essay, secernate it on our website: OrderEssay.net
