Data = new DenseMatrix(RawData); //RawData is a 2D double array (77 observations X 11 variables)
FactorAnalysis F = new FactorAnalysis(Data,5);
F.S(); // gives the same correlation matrix as in SAS, so it is totally fine.
F.nFactors(); //=5, so again totally fine
F.nVariables(); //Gives 11 variables, again totally fine.
F.getEstimators(100); //crashes with the aforementioned error. `
Thanks in advance for your help and support.
