It is the last semicolon, which supresses output.

But it has some other problems.

Although I have been using Mathematica for a while I still consider myself a rookie.   Could someone explain what I am doing wrong with the following code, please?

sum=RandomVariate[FRatioDistribution[2,2 \[CurlyPhi]],np];
Do[sum=sum+RandomVariate[FRatioDistribution[2,2 =
Histogram[sum,{Min[sum],Max[sum],1},"PDF",AspectRatio->1/3,PlotRange-> {{Min[sum],Max[sum]},All},ImageSize->Large],
{{\[CurlyPhi],5,"parameter"},1,1000, Appearance->"Labeled"},
{{np,1000,"number of data points"},1,1000000, Appearance->"Labeled"},{{nr,20,"number of replications"},5,10000, Appearance->"Labeled"}];

Nothing shows up.

Is there a faster way to implement the summation?

Many many thanks
