Surprise when mapping matrix to image
Hello,
I wonder if
image(t(x)[ncol(x):1, ])
can do the job correct!
perhaps this does the job better:
image(t(x)[,nrow(x):1])

ML fit of pareto and lognormal distributions to grouped data
...mma
distribution ML fitting for grouped data.
I just wonder if there is any method that works for lognormal or
pareto distribution?
An example would be:
Ranges<-c(0,50,100,150,200,250,300,400,500,750,1000)
Claims<-c(452,62,95,88,118,118,261,367,972,982,3024)

Which Solaris is this? I am not seeing any problems with our Solaris 8
systems. Was the compiler built on that exact system? What gcc options
