Statistics 1

R demos (thanks to Peter J. Green)

Histograms and density functions (section 2): show.R
Sampling and parametric inference (section 3): popsamp.R
Likelihood and MLE (section 3): likelihood.R
Least squares linear regression (section 4): regression.R
Comparing estimators in Uniform distribution (section 5): unif.ests.R
Exact distributions of sums of i.i.d. rv's, and CLT (section 5): clt.R
Confidence intervals (section 7): ci.R
Test for population mean of a normal distribution (section 8): test.mean.R
Normal linear regression (section 9): norm.reg.R

You can download any of these R source files to your computer, and run them later. Alternatively, if you stay online, you can load each individual file directly into R by typing, for example,
source("http://people.maths.bris.ac.uk/~maxca/stats1/downloads/show.R")
for the function corresponding to section 2 and then run the functions immediately (note that if you cut and paste, some of the characters may be changed and R may not understand e.g. in my case quotes were changed to quotes R does not like).
