Determining the number of active and kill bits to set to mimic a given project is more involved. Earlier we fitted a 2 normal mixture to the activity distribution of a real project which yields 2 means (locations), 2 standard deviations (spreads) and a mixing parameter that gives the contributions of the two normal distributions to the overall mixed distribution. Applying the same technique to the outputs from eight simulations with a range of parameters (numbers of active bits varied between 5 and 40, kill bits between 1 and 10) and fitting the mixed normal distributions yields the following relationships (figure ): -
