Derzeit ich mit dieser Funktion in R am Experimentieren:berechnen Gibbs Sampler (Albert und Chib) für Binary Probit für 2 y Vektoren
rbprobitGibbs(Data, Prior, Mcmc)
Wenn ich durch das Beispiel in der RStudio Hilfe gehen für rbprobitGibbs es, einen n * 1 y Vektor mit diesem Code:
##
## rbprobitGibbs example
##
if(nchar(Sys.getenv("LONG_TEST")) != 0) {R=2000} else {R=10}
set.seed(66)
simbprobit=
function(X,beta) {
## function to simulate from binary probit including x variable
y=ifelse((X%*%beta+rnorm(nrow(X)))<0,0,1)
list(X=X,y=y,beta=beta)
}
nobs=200
X=cbind(rep(1,nobs),runif(nobs),runif(nobs))
beta=c(0,1,-1)
nvar=ncol(X)
simout=simbprobit(X,beta)
Data1=list(X=simout$X,y=simout$y)
Mcmc1=list(R=R,keep=1)
out=rbprobitGibbs(Data=Data1,Mcmc=Mcmc1)
summary(out$betadraw,tvalues=beta)
if(0){
## plotting example
plot(out$betadraw,tvalues=beta)
}
Könnte jemand bitte sagen Sie mir, wie würde ich den obigen Code aktualisieren, um die rbprobitGibbs statt mit 2 oder wirklich einem beliebigen Anzahl von y-Vektoren zu berechnen? Die ersten vier Spalten hier sind die Daten aus der Probe, mit der y2-Säule ist die, die ich hinzugefügt:

UPDATE:
FYI, das ist das Buch arbeite ich durch:
http://ca.wiley.com/WileyCDA/WileyTitle/productCd-0470863676.html
Ich denke, Sie müssten dies selbst codieren. Stan, JAGs oder * Bugs wären Optionen. –
OK, ich habe wirklich keine Ahnung, wo ich anfangen soll. Ich bin ziemlich neu für R und Statistik im Allgemeinen, da ich nur einen Kurs belegt habe. Was meinst du mit "Stan, JAGs oder * Bugs"? – Roger
