WebWhile FindDistributionParameters might provide a reasonable "fit" that well describes the observed data (a mixture of two or more normals for example), there is no random sampling from a mixture of normal distributions or a mixture of Poisson distributions. WebMar 18, 2013 · Here is the code model = a*Cos [b*t + c]; fit = NonlinearModelFit [data, model, {a, b, c}, t, Method -> NMinimize] When I use the command: fit ["BestFitParameters"] the values are returned in the following format: {a -> 1, b -> 2, c -> -3} Now i want to store the value of a in a variable x x=fit ["BestFitParameters"] [ [1]] but this gives x= a -> 1 ethinyl estradiol with pentobarbital https://maamoskitchen.com

As mentioned, we have applied a Computer Algebra System (CAS), particularly Mathematica to carry out the needed symbolic and numeric computations. And hence, codes are crafted in Mathematica language. Interested readers may apply the codes producing our result.

WebThe primary differences are that FindFit: (1) recognizes EDA 's data format, including errors in both coordinates; (2) estimates errors in fit parameters; (3) by default displays graphical information about the fit; and (4) uses an algorithm that has been optimized for speed and stability for the types of nonlinear fits commonly performed in the …
