Hello, I am a student in Paris and I encounter some difficulties in programming R. I have one data frame made up of 4 columns and 250 lines and whose each line is a family. I made a random pulling with handing-over of the families 250 times what brings me to a new dataframe. With this new dataframe, I apply a program which calculates 2 parameters X1 and X2. I start again, 2000 times, and at the end : I obtains 2000 values of X1 and X2. With that I know the empirical law of X1 and X2 and I determine a confidence interval of X1 and X2. The problem is that I do not know draw the ellipso?de confidence (region confidence) . I have download the package ellipse but I do not see. Can you help me please ?? I thank you in advance. Cordially, Hamida MOHAMDI _________________________________________________________________ Pro ou perso, toutes les adresses et num?ros de t?l que vous cherchez
