Phylogenetic autocorrelation: Difference between revisions

'''Galton's problem''', named after Sir [[Francis Galton]], is the problem of drawing inferences from [[Cross-cultural studies|cross-cultural]] data, due to the statistical phenomenon now called [[autocorrelation]]. The problem is now recognized as a general one that applies to all nonexperimental studies and to [[experimental design]] as well. It is most simply described as the problem of external dependencies in making statistical estimates when the elements sampled are not [[statistical independence|statistically independent]].
