Statistical tests are used in circumstances in which an unequivocal answer cannot be established. If cells always die when oxygen is cut off, we do not need a statistical test to establish that they require oxygen to live.Statistical significancesays something like: “Odds are pretty good that ...
Of course, there are certainly situations where a zero-inflated model makes sense from the point of view of theory or common sense. For example, if the dependent variable is number of children ever born to a sample of 50-year-old women, it is reasonable to suppose that some women are bi...
We found that the proportion of the diagnoses of 'autistic tendencies' had a statistically significant increase of 2.04-fold from 1998 to 2012, with an adjusted odds ratio of 2.36 per decade (95% CI: 1.78 to 3.12, P value of 2.3e-09, GEE model) (Figure 4A, [see Additional file 1: ...
This came up in a discussion a few years ago, where people were arguing about the meaning of probability: is it long-run frequency, is it subjective belief, is it betting odds, etc? Iwrote: Probability is a mathematical concept. I think Martha Smith’sanalogyto points, lines, and arithme...
To determine whether a given gene-pair is involved in drug resistance, we calculated a simple odds ratio of the corresponding two posterior probabilities: odds=Pr(Yij1R=1)Pr(Yij1P=1) ((10)) where, Yij1R and Yij1P are gene-gene relationships defined over resistant and parental networks...
What’s one to make of the stream of “eat this,”“avoid that” studies surfacing nearly daily? It’s an odds-on bet that readers will find out in the complete Science News story, “Odds Are, It’s Wrong.” As we tell Monty that we’ll take what’s behind Door #2, we might ...
This independence from initial conditions not only decreases the odds of converging to a local rather than global optimum but also allows for optimization of objective functions that are discontinuous, as can occur in statistical population reconstruction. As expected, simulated reconstructions that used ...
