L moment for Gruped/Classed data
Hi all.. I am studying the possibility to use the L moment to estimate the parameters of gamma distribution. Almost in all papers, it is explained that the parameters of exponential, gamma and lognormal distribution can be calculated by combining two L moments (for example, L1 and L2). L1 and L2 are in function o... 4 Mar 2010 13:28

Problem with plotting local Maxima and Minima of CWT.
Hi Everyone, For my application i need to find out the Local Maxima and Minima of the any 1D data.

chi2test - false df and edges
hi everyone! if have the following problem - when i use the chi2test with [h,p,st] = chi2gof(chi_vec2,'edges',edges,'expected',expectedCounts); and the bin-size (interval size) is reduced to 5, then the edges and df aren't correct. when i have 10 bins with the width of 5, e.g., then the expected and observed c... 5 Mar 2010 15:04

Coefficient "fixed at bound" when it shouldn't be
Hi there, I'm fitting some data to an equation, which has 3 variables, k1, k2 and tau. I have an estimated value for tau which I have read from the data earlier in the code, which is placed in the variable "tau". I wish to tell the fit function that the starting point for searching for a value of tau is the value wi... 4 Mar 2010 11:11
