This code generates a Normal distributed variable. This cofde generates 12 (it's an importnat number) uniformly distributed variables (Xs)between -100 and 100 and adds them into a 1000 sample vector called gausian. Of course, you can play with the parameters to satisfy your demands, but the important things are: 1) if you give Xs asymetric range , and you want a normal (i.e mean=0) distribution, don't forget to substract range_size/2 from every sample. 2) The number 12 gives the std 1 because a uniform std is 0.25 =~sqrt(1/12) and by adding 12 Xs you obtain std=1 so if you change this number be sure to modify your std as well. 3) I gave an example with 1000 points. Of course, the more points-the more accurte distribution, but longer run. The code includes coverage so that if you run it with specview and open the coverage window and look at samples ( under normal.collect) you can see graghically the distribution (flipped to the side) author: Avi Farjoun updated 10/28/2004 1071 bytes
