Reconstruction of the factors matrix for the Hemoglobin data. Shown are (a) the reconstructed profiles given by algorithm Z, (b) the reconstructed profiles given by algorithm U, (c) the reconstructed profiles given by algorithm F, (d) the reconstructed profiles given by algorithm W, and (e) the reconstructed profiles given by algorithm M. The positions of the zero entries in the loadings matrix are not given a priori. The light gray curves are the profiles given by the 20 different Gibbs sampling runs, and the black curves are the average profiles. We also plot with gray the true profiles for an easier comparison. These profiles are obtained after performing varimax rotation on the factor loadings matrix.
