Functions
AlgError	AlgMixtureMLG (int nDbn, int nCls, double samOrg, double samItv, double *freq, double *alpha, double *mu, double *sd, double tol, double sumFreq, double *dstLL, int *dstNItn)
	Computes the maximum liklihood estimate of the parameters of a mixture of normal distributions which best fit the give frequencies. These parameters are the miximg proportions, means, and standard deviations. The log-liklihood and the number of iterations are also computed. This algorithm is based on the article: Agha M. and Ibrahim M.T. Maximum Liklihood Estimation of Mixtures of Distributions AS203 Applied Statistics 33(3):327-332, 1984. More...
AlgError	AlgMixtureSyn (int nCls, int *synFreq, int nObv, double synOrg, double synStep, int nDbn, double *alpha, double *mu, double *sigma)
	Synthesise a mixture of normal distributions. More...
