PDFPROPS Mean and variance associated with a probability distribution. [MU,SIGMA]=PDFPROPS(X,FX), given a probability distribution function FX over values X, returns the mean MU and the standard deviation SIGMA. The statistics are computed using a trapezoidal integration. FX is multiplied by a constant so that it integrates to one. [MU,SIGMA,SKEW,KURT]=PDFPROPS(X,FX) also retuns the skewness and the kurtosis, which are the third and fourth central moments, respectively normalized by the third and fourth powers of the standard deviation. PDFPROPS(X,FX,DIM) alternately computes moments along dimension DIM. By default, DIM=1, so the moments are computed along rows. 'pdfprops --t' runs a test. Usage: [mu,sigma]=pdfprops(x,fx); [mu,sigma,skew,kurt]=pdfprops(x,fx); [mu,sigma,skew,kurt]=pdfprops(x,fx,dim); __________________________________________________________________ This is part of JLAB --- type 'help jlab' for more information (C) 2001--2013 J.M.
