| WinBUGS is one of the usual softwares in computational Bayesian statistics, which is used to fit Baysian models easily. Although this software has usual mathematical functions and statistical distributions as built in functions, sometimes it is necessary to include other functions and distributions in computations which is done by some tricks and indirectly. By using WinBUGS development interface (known as WBDev), new mathematical functions and statistical distributions can be added in the software. This method facilitates writing codes of statistical models, increases speed of computations and make computations more efficient. In this paper, the stages of including new mathematical functions and statistical distributions in the WinBUGS are illustrated by some examples. |
