Arguments

medianfit

The output of a fitdist command following elicitation of the expert's beliefs about the population median.

precisionfit

The output of a fitdist command following elicitation of the expert's beliefs about the population precision.

lower

lower limit on the x-axis for plotting.

upper

upper limit on the x-axis for plotting.

ql

lower quantile for the plotted pointwise credible interval.

qu

upper quantile for the plotted pointwise credible interval.

median.dist

The fitted distribution for the population median. Can be one of "normal", "lognormal" or "best", where "best" will select the best fitting out of normal and lognormal.

precision.dist

The fitted distribution for the population precision. Can either be "gamma" or "lognormal".

n.rep

The number of randomly sampled CDFs used to estimated the median and credible interval.

n.X

The number of points on the x-axis at which the CDF is evaluated.

fontsize

Font size used in the plots.
