Dataset of means and std

TW16 — Fri, 10 Mar 2017 17:39:11 GMT

i have a data set of means, stds, min and max. I want to explore the data utilizing all the information i have...ie incorporating the standard deviation along with the means. How do i do that. I don't have the raw data for each mean or std.

What kind of research questions are you trying to answer.

You don't mention whether you have the n (count of subjects) any of those stats are based on. That may make things very hard much with.

I am trying to evaluate the distribution, see outliers, see if a process is
under control, observe corrilations and evaluate capabilities. I am
assuming n is the same for all.

It is about data simulation.
Better post it at IML forum.

use rand() you can get normal distribution with a special mean and std.
once the data are out the range min-max , throw it out the window.
data have;
do i=1 to 10000;
x=rand('nomal',mean,std);
if min<=x<=max then output;
end;
run;
