[R] Help on Heteroskedastic diagram
Hi, I am trying to create a diagram similar to Figures 4.4 (page 125) and 5.2 (page 159) in Stock and Watson2009) Introduction to Econometrics Brief Edition. The diagrams display the conditional probability distributions of y at different values of x along the regression line. I would be grateful if anyone could enlighten me on to create such a diagram in R. Thanks in advance and have a nice weekend. regards Al __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
