Comparison of genotypes and checking time trend
Description
Data are plant height of barley measured in cm. Averaged over 4 replicates for 15 genotypes. It is of interest if there is any difference in genotypes and also if there is any time trend in heights for the same genotype. Further, one may check if trend is similar across genotypes. It is of interest to explain height using weather information.
