Gary Venter’s age-period-cohort decomposition of US male mortality trends

Following up on yesterday’s post on mortality trends, I wanted to share with you a research note by actuary Gary Venter, “A Quick Look at Cohort Effects in US Male Mortality.” Venter produces this graph: And he writes: Cohort effects in mortality tend to be difficult to explain. Often strings of coincidences are invoked – […] The post Gary Venter’s age-period-cohort decomposition of US male mortality trends appeared first on…

“Cancer Research Is Broken”

April 20, 2016
By

Michael Oakes pointed me to this excellent news article by Daniel Engber, subtitled, “There’s a replication crisis in biomedicine—and no one even knows how deep it runs.” Engber suggests that the replication problem in biomedical research is worse than the much-publicized replication problem in psychology. One reason, which I didn’t see Engber discussing, is financial […] The post “Cancer Research Is Broken” appeared first on Statistical Modeling, Causal Inference, and…

Ethan Bolker points me to this news article by Neil Irwin: Robert J. Gordon, an economist at Northwestern University, has his own version that he argues explains inflation levels throughout recent decades. But it is hardly simple. Its prediction for inflation relies not just on joblessness but also on measures of productivity growth, six shifts […] The post “if you add a few more variables, you can do a better…

Michael Smith writes: I have a research challenge and I was hoping you could spare a minute of your time. I hope it isn’t a bother—I first came across you when I saw your post on how psychology researchers can learn from statisticians.
