The first link explains the context or why it is important for Peter Frost to maintain that West/Central Africans and African-Americans have higher testosterone levels than white men. You said that you are not familiar with regression analysis. So how can you be so sure that Peter Frost has refuted my arguments? Let us look at his arguments. Testosterone and white male – West African male differences Frost has a strange interpretation of age-adjusted values. When someone talks about reporting values that have been adjusted for age, it means that all ages have been taken into consideration. Just because the authors choose to present the hormone level statistics by three broad age groups, it doesn’t mean that the hormone values are adjusted for membership in one of the three age groups. A related point by him is that “the black-white difference in t levels shrinks after 24 years of age, is gone by the early 30s, and seems to reverse at older ages,” but given that the literature has shown results all over the map and null finds, how can he use one study, using non-representative sampling, to insist on this statement so definitively? And the reason he brings out this point is because of his misinterpretation that the age adjustment was by broad age group rather than all ages. This mistake also prompts him to invoke [small] differences in median ages between the groups. https://its.fh-campuswien.ac.at/hackmd/s/JnqeNil1t https://hackmd.iscpif.fr/s/rkrmhM1oxg https://hackmd.diverse-team.fr/s/rydHg-740 https://md.ccc-mannheim.de/s/SJySFt09lx http://tacheles.humanistika.org/s/rJlpebt0eg https://hackmd.astamuse.net/s/SJvV8w5ngl https://hackmd.stuve-bamberg.de/s/x-bffabI0 https://docs.snowdrift.coop/s/6vwMFFiPc https://hedgedoc.catgirl.cloud/s/I34Ez6Gd5 https://hackmd.bangumi.org/s/rkx7HZJehxl https://pad.demokratie-dialog.de/s/oVGf7S7L11 https://hackmd.stuve-bamberg.de/s/hRZ-myP9C https://craigslist-personals.eurolines.nl/ https://craigslist-personals.mijnstartonline.nl/ https://craigslist-personals.rosadoc.be/ https://craigslist-personals.de-vitrine.be/ https://craigslist-personals.velelinkjes.nl/ https://craigslist-personals.maakjestart.nl/ https://craigslist-personals.gratislinken.nl/ https://craigslist-personals.backlinkplaatsen.nl/
