196Mean value, <img class="formulaInl" alt="$\mu$" src="form_75.png">, of this density is given by a geometric combination of <code>rvc</code> and given fixed point, <img class="formulaInl" alt="$p$" src="form_66.png">. <img class="formulaInl" alt="$l$" src="form_85.png"> is the coefficient of the geometric combimation <p class="formulaDsp">

200Standard deviation of the random walk is proportional to one <img class="formulaInl" alt="$k$" src="form_76.png">-th the mean. This is achieved by setting <img class="formulaInl" alt="$\alpha=k$" src="form_77.png"> and <img class="formulaInl" alt="$\beta=k/\mu$" src="form_78.png">.<p>
201The standard deviation of the walk is then: <img class="formulaInl" alt="$\mu/\sqrt(k)$" src="form_79.png">. <hr><h2>Member Function Documentation</h2>
