MCMC Pack Crashes R-GUI session (PR#9516)
...frame and set my object.size = 1 gigB.
Despite my best efforts it still crashes while advising me to contact the MCMC
Pack developement team.
I am running windows XP with R version 2.4.1.c (the latest).
Here's the offending instruction in R:
mcmcReg<-MCMCSVDreg( jpMorganChase.Adj.Close ~ exxon.Oil.Volume+usSteel.Volume,
data=yy.lo.res.scaled[ 2000:2274, ], burnin = 100, mcmc = 1000,
thin=1, verbose = 1, seed = NA, tau2.start = 1,
g0 = 0, a0 = 0.01, b0 = 0.01, c0=2, d0=2, w0=1,
beta.samp=TRUE, intercept=TRUE )
Here's the error msg:
