Dear Stata Members
I would like to ask a few questions and clear some doubts regarding regressions but for that, I need to create some random variables with some pre-defined correlations. So please help me to create some panel data with 4 four variables (v1,v2,v3, & v4) that has the following correlations
1. v1 and v2 (0 correlation)
2. v2 and v3 (some positive .50 to .60 correlation)
3. v2 and v4 (some negative .50 to .60 correlation
4. v3 & v4 (some low correlation 0.05-.12)
150-200 observations will be fine and if the panel is not easy then let these variables be some time series ones.

Did I make sense by asking the question? These artificially created variable can help me in testing some assumptions of OLS. I tried excel but couldn't meet these requirements.
