Simulate, model, and display data from a time-course microarray experiment with periodic gene expression Fit models for periodic gene expression to time-course microarray data in a normal mixture model framework with mean approximated by a truncated Fourier series and covariance structure modeled by an ARMA(p,q) process. Estimation is performed with the EM algorithm.
