Density functions
Description
Density functions for the model parameter. fp(a,sd) is the normal density: 1/(sd*sqrt(2*pi))*exp(-(a^2)/(2*sd^2)). ft and fl are the exponential density (with a fixed rate = 1): exp(-a).
Usage
fp(a, sd)
ft(a)
fl(a)
Arguments
a |
Parameter. |
sd |
Standard deviation. |
Value
Numeric value of the computed density.
