... Figure 4 shows the mean bias and the standard deviation around the mean for the sites-heights available. Bias values have been binned in 10m steps (left plot) and also all together (right plot). The variability for each height bin is shown with error bars reflecting the standard deviation on the bia ...

... The three points just found, plus the fact that the respondent’s recall cumulative distribution function (cdf) must be bounded by 0 and 1, give us 5 points that define the recall cdf quite well. We can now readily develop the corresponding probability density function. The resulting prior density c ...

... This is approximate for a number of reasons. First of all, we are trying to make an all-purpose statement that really might not apply perfectly to everything. Also, the “2” should really be 1.96, which has the property that P[ -1.96 ≤ Z ≤ 1.96 ] = 0.95 for a standard normal random variable Z. One ca ...
