Hi Group,
I have GCRMA normalised Affymetrix dataset.With this I wanted to find
present and absent probes using Gaussian mixture model,by creating 2
Gaussian probability density function,one for present and the other for
absent.The probes whose average intensity across all the samples, larger
than threshold value where the 2 gaussian PDFs meet is to be considered as
present.
To do the analysis I was suggested to use Mclust package. But could anyone
suggest some fuctions in the package that would be useful in this task on
which I could focus on.
Thanks,
Viritha
