Splus Notes  

Notes  Preliminary version of what became Venables' & Ripley's Modern Applied Statistics with Splus 

Splus Code  
sim1.s  Various functions for generating random numbers  
mc.s  Various functions for generating finite state Markov chains  
example0.s  An example where "specifying" full conditionals doesn't lead to a unique stationary distribution  
example1.s  An example of a nonparametric regression using a random walk prior  
example2.s  An example of a nonparametric regression using a locally quadratic prior  
nbhood.s  Finding the weights for locally quadratic Gaussian autoregressions on the 2D lattice  
fieldtrial.s  Analysis of a corn variety trial conducted by the state of North Carolina. A locally planar Gaussian MRF is used to account for 2D spatial fertility. The yields are in yield.dat and the variety labels are in variety.dat.  
example3.s  An example of a nonparametric regression using a Gaussian process prior  
poissonreg.s  An example of simple Poisson regression using the identity and log links.  
texture.s  A program to simulate a 12 nearest neighbor Gaussian MRF using Gibbs sampling. This file makes textures of ocean, wood, wool, etc. The function genfield() calls a C routine in the file genfield.c. This file in turn requires the C routines in the file randomS.c and getnbhd.c. <\TD>  
bintexture.s  An example of using psuedolikelihood to estimate coefficients of an autologistic function from a binary texture image in the file bintex.dat.  
gensurf.s  Splus code for doing all of the continuous Gaussian random field stuff in the notes on continuous fields: spatial.ps.  
varioest.s  Code for looking at variograms.
