evolgen | January 14, 2006Nucleotide Polymorphism and Selection
This is the seventh of multiple postings I plan to write about detecting natural selection using molecular data (ie, DNA sequences). The introduction can be found here. The first post described the organization of the genome, and the second described the organization of genes. The third post described codon based models for detecting selection, and the fourth detailed how relative rates can be used to detect changes in selective pressure. The fifth post dealt with classical population genetics methods for detecting selection using allele and genotype…
tlambert | April 16, 2004 A couple of days ago, I told the story of GEP, how a tobacco company tried to get epidemiologists to adopt a bogus principle that risk factors of less than 2should be ignored. I noted that Iain Murray was still peddling this bogus principle in a Tech Central Station article. That wasn't the only time Murray had tried advancing the tobacco company's risk-factor-of-two principle. He also did it in this Tech Central Station article, which prompted an actual epidemiologist to send him the following email:
Thank you for your thoughtful article "…
