What’s the probability that Daniel Murphy hits a home run tonight?

20% 15%, that’s my quick empirical estimate. Where do I get this? I googled *most home runs hit in consecutive games* and found this list of players who’ve hit home runs in at least six consecutive games. There are 20 such cases; 14 of these streaks ended at six games, and 6 of these streaks […] The post What’s the probability that Daniel Murphy hits a home run tonight? appeared…

It’s all about the denominator:  Rajiv Sethi and Sendhil Mullainathan in a statistical debate on racial bias in police killings

Rajiv Sethi points me to this column by Sendhil Mullainathan, who writes: Tamir Rice. Eric Garner. Walter Scott. Michael Brown. Each killing raises a disturbing question: Would any of these people have been killed by police officers if they had been white? . . . There is ample statistical evidence of large and persistent racial […] The post It’s all about the denominator: Rajiv Sethi and Sendhil Mullainathan in a…

Simulate contingency tables with fixed row and column sums in SAS

How do you simulate a contingency table that has a specified row and column sum? Last week I showed how to simulate a random 2 x 2 contingency table when the marginal frequencies are specified. This article generalizes to random r x c frequency tables (also called cross-tabulations) that have the same marginal row […] The post Simulate contingency tables with fixed row and column sums in SAS appeared first on The DO Loop.

We need a statistically rigorous and scientifically meaningful definition of replication

Although some press releases try to convince us otherwise, rarely is one publication enough. In fact, most published results go unnoticed and no attempts to replicate them are made.  These
