189Inverse-Gamma random walk.
190<p>
191Mean value, <img class="formulaInl" alt="$ \mu $" src="form_80.png">, of this density is given by <code>rvc</code> . Standard deviation of the random walk is proportional to one <img class="formulaInl" alt="$ k $" src="form_81.png">-th the mean. This is achieved by setting <img class="formulaInl" alt="$ \alpha=\mu/k^2+2 $" src="form_82.png"> and <img class="formulaInl" alt="$ \beta=\mu(\alpha-1)$" src="form_83.png">.<p>
192The standard deviation of the walk is then: <img class="formulaInl" alt="$ \mu/\sqrt(k)$" src="form_84.png">. <hr><h2>Member Function Documentation</h2>
