On the apparent clustering of clonal albumin production and enzyme activity levels.
This communication is a critique of a novel, but inappropriate, use of the correlation coefficient to demonstrate the clustering of biological activity levels about a purported geometric progression. The data are re-examined by using a Fourier analysis approach to test for periodicity on a logarithmic scale; this approach follows from the methods of Kendall (1974, Philosophical Transactions of the Royal Society, Series A 276, 231-266) and Fisher (1929, Proceedings of the Royal Statistical Society, Series A 125, 54-59).
