...d here is the simple function FitModels(), if you care to see it.
It was extracted from a much larger function that computes several other
covariates from x1 and x2:
FitModels <- function(vnames,dframe,survname,censname,censval="Progressed"){
## Get covariate x1 from data frame:
x1x1 <- eval(parse(text=paste(dframe,vnames[1],sep="$")))
## Get covariate x2 from data frame:
x2x2 <- eval(parse(text=paste(dframe,vnames[2],sep="$")))
## Get survival time:
response <- eval(parse(text=paste(dframe,survname,sep="$")))
## Get censor...

...dea is that T_ATTENT
mediates the effect of FARSCH and LOCUS10 on RMTEST. The RAM
specification I used is
FARSCH -> T_ATTENT, y1x1, NA
LOCUS10 -> T_ATTENT, y1x2, NA
FARSCH -> RMTEST10, y2x1, NA
LOCUS10 -> RMTEST10, y2x2, NA
T_ATTENT -> RMTEST10, y2y1, NA
FARSCH <-> FARSCH, x1x1, NA
LOCUS10 <-> LOCUS10, x2x2, NA
T_ATTENT <-> T_ATTENT, y1y1, NA
RMTEST10 <-> RMTEST10, y2y2, NA
LOCUS10 <-> FARSCH, x2x1, NA
This model runs, but using the summary function does not return the
usual model fit statistics, only the following:
