Summary values for α and β
The distributions over α and β give us a full picture
of these parameters: a probability for each value in the bin, that that parameter value generated the observed data.
However, for our analysis we usually we want a single estimate for α and β.
How would you go about obtaining this from the distributions plotted on the previous page?
Let's have a look at how well this model is performing. In the original trial-by-trial dataplot, we now added the estimated choice probabilities (in turquoise)
