Subject maximum number of iterations reached
Date Tue, 15 Mar 2011 08:36:53 GMT
When using NormalDistributionImpl calss, I encounter the error throwing message

org.apache.commons.math.ConvergenceException: maximum number of
iterations reached

The value provided in cumulativeProbability is a double of current
time subtracting previous timestamped e.g. t_now - t_prev

What might cause this issue or how to fix it?

Thanks.
