Examples of genes with the same LU regression pattern but in different k-means clusters. a. Bzrp is an example from k-means cluster K2; b. Aqp1 is an example from k-means cluster K5; c. Prg is an example from k-means cluster K6; d. Hnrpl is an example from k-means cluster K8. These 4 genes are all identified to have the LU regression pattern, but in 4 different k-means clusters. The LU regression pattern is clearly a good fit to the temporal expression profiles of these 4 genes. The horizontal axis is the log transformation of time. The blue dots are the signals. The green line is the connection of the mean signal at each time point. The red line is the LU regression pattern.
