The default value of the coefficient of variation threshold that is used to check if the distribution has converged. This value is used to compute standard deviation thresholds based on the current mean estimates. The default value is 0.03, which is considered a narrow or tight distribution.

This can be used to globally increase/decrease the variability associated with the initial parameter setting. For example, a value of 1.1 increases the starting standard deviations by 10%. The setting must be a positive value. The default value is specified as 1.0.
