search for: approximaly

...bout the results I get. In fact, I start with a uniform sample between -1 and 1, and then plot its density. My problem is that the density ranges are much more longer than I expected : samp <- runif(10000,-1,1) plot(density(samp)) Instead of varying between -1 and 1, the density varies between approximaly -1.5 and 1.5 Could someone explain me what is happening ? Maybe some arguments for density estimation need to be set ? Waiting for an answer, Thanks in advance Isabelle. Isabelle Zabalza-Mezghani, PhD IFP - Research Reservoir Engineer
