A Reexamination of the Cell-Lineage Data of E. P. Powell Academic Article uri icon

abstract

  • E. O. Powell carried out numerous experiments observing cell-generation times on bacteria. His statistical methodology, though quite advanced 40 years ago, can be enhanced by better models of dependence, by advanced computational methods, and by judicious use of robust methods. We reexamine Powell's data, focussing on his main interest in establishing whether there were indeed dependencies in generation times between cells with close filial connections.
