Dec 22, 2014 at 20:02 | comment | added | StasK | If you want to argue that Bayesian approach is more applicable to small samples of size $n=1$, then it is inevitable that prior will speak way too loudly with such a sample. | |

Dec 22, 2014 at 19:08 | comment | added | Constantin | I'm looking for evidence in support of my assumption that the event examined has an influence on the stock price (in which case the $CAR$ is different from zero, because it is computed during the event window, relative to the normal return, which is computed for the reference period before the event). I am interested in whether the data supports the hypothesis that there is indeed a non-zero $CAR$ and also in its magnitude. I realise statistical significance isn't really a thing in Bayesian statistics but what interpretation does this method offer? Can I apply a hypothesis testing equivalent? | |
Dec 22, 2014 at 12:34 | comment | added | Andy Jones | (1.) is simple: use Bayesian linear regression. (2.) is more tricky, because significance testing isn't a Bayesian thing. The only thing you can do is compare the probability of different models, and $\text{CAR} = 0$ isn't the basis of a model because $\text{CAR}$ isn't a model parameter. What's the purpose of the $\text{CAR}$? What decisions are made based on it? | |
