I am repeating this because it seems that some people think it is important to reveal your identity I don;t understand why this is so important.   Hopefuly now this list will be helpful.

Could someone please assist with this


I am trying to understand how to use the flexmix package, I have read the Leisch paper but am very unclear what is needed for the M-step driver.  I am just fitting a simple linear regression model.  The documentation is far from clear what the FLXmclust function does, but, it in principle could do all I need, however, I do not get sentible results as if I try the following the result is poor:

x<-c()
for(i in 0:99){x$y[2*i]=(0+i);x$x[2*i]=i;x$x[2*i+1]=i;x$y[2*i+1]=i+1000;x$g[2*i]=1;x$g[2*i+1]=2}
m1<-flexmix(y~x  ,data=x,k=2)
table(x$g,m1@cluster)

1  2
1 25 74
2 67 33

It all depends on the randomised starting values.  So I think I need a better "driver", but, I cannot find a spec for what I have to do in the driver.

Where is FLXmclust documented?  can anyone assist?
