Interesting problem: Use of NonlinearRegress inside a package

Hello, I created the following package: Off[General::spell]; Off[General::spell1]; BeginPackage["Test`", {"Statistics`NonlinearFit`"}]; f::usage = "test NonlinearRegress inside a package"; Begin["`Private`"]; f[data_] := Module[{model, a, b, x, fit}, Print["The context of NonlinearRegress is ", Context[NonlinearRegress]]; Print["The context of BestFit is ", Context[Bestfit]]; model = a*x + b; fit = NonlinearRegress[data, model, {x}, {a, b}, RegressionReport ->{BestFit, ParameterTable, FitResiduals}]; Return[fit]; ]; End[]; EndPackage[]; In[8]:=?f test NonlinearRegress inside a package In[9]:=data={{0.8493`,2.015`},{2.3355`,2.267`},{4.8832`,2.589`},{7.2187`, 2.812`}}; In[10]:=f[data] The problem is that, inside the Module f I wanted to see the BestFit, ParameterTable and FitResiduals, but since these are known only to Test`Private`, what Out[10] does is it treats the NonlinearRegress as if the option RegressionReport was not specified! I know that this problem is related to the Context of the symbols/names, but don't know how to get around it (I'd really like to keep the Module inside the Private section of the package). Perhaps someone could help me? Thanks a lot, Hoa
