>From basic statistics principle,we know,given several i.i.d Gaussian RVs with zero or nonzero mean,the sum of square of them is a central or noncentral Chi-distributed RV.However if these Gaussian RVs have different variances...
Currently, I am intrested in parameter fitting of "Generalized Lambda Distribution".And I have found two packages in R related to Gld,Davies and gld. What's a pity that no method in Davies deals with fitting of gld,and...
Thanks a lot. It does work. The fitted data match the simulated ones well. Even no need the shifted or scaled version of Chi-squared pdf. Also, I have tested the case of non-independent RVs,generated by linear combining...
A doubt: Multiplying together the characteristics functions is available only if all a(i)|R(i)| is independent,i think.However, obviously, that is not true herein. I will try the methods you mentioned.Thanks a lot! 2003-04-14...
