Thanks a lot Rhoit! I think it's good.
Thanks Jim! I didn't though to use a mixture model. Pretty long, but it works: S = StableDistribution[\[Alpha], \[Beta], \[Mu], \[Sigma]] /. mle[]; Print@Show[{Histogram[don, "FreedmanDiaconis", "PDF", PlotRange ->...
Hello! According to the documentation, "it is also known as autocorrelation or cross-correlation function (ACF or CCF)" . Consider two series: don2 = {1.4700335660303452, 3.938502200833952, -2.3409981833059916,...
Hello everybody! I'd like to compute a cross-correlation function between two series, and tests the associated correlations. So , I installed the R package testcorr, and tried to use it. Here are the data - X and Y: {-642.004, 868.033,...
Hi Ted! The problem is that DiracDelta is not really a function, but a positive measure (or, more generally a Schwartz's distribution). So, we must use a sequence of functions converging towards DiracDelta to obtain the Laplace Transform. Try for...
Hello! Try something like: Needs["MultivariateStatistics"]; data = RandomReal[MultinormalDistribution[{1, 15}, v], {1000}]; \[CapitalOmega] = EllipsoidQuantile[data, 0.95]; Show[ListPlot[data, Frame -> True, AspectRatio ->...
Hi! I tried to simply your problem, using the linearity of the integral. First, IntegListe = Apply[List, ExpandAll[ K*(a*K*Exp[-(a + ((g*(1 - c*g))*(L/(1 + (L - 1)*Exp[-(t - T)])))/ K)*t] + (g*(1...
Thank you very much! LeTexte = Import["UEMO2021.txt", {"Text", "Lines"}, CharacterEncoding -> "WindowsANSI"]; works perfectly! Regards, Claude
Hi! Can I apply textual analysis methods (in Mathematica 12.1) to French texts? I translated few sentences in English, processed them and back-translated the result, but remember it was the favorite method of Père Ubu to convert an old...
You wrote "I normally use the means of the bins as predictor (independent) variables, but I want to use the variances of the bins too". Maybe it would be interesting for you to use quantile regression to obtain such a predictor? See : ...
