Hi Statalist members

I would like to ask: How to obtain a robust correlation/ covariance matrix?

Suppose there is a data panel as follow:
x1 x2 x3 x4 x5 x6 x7
0 1 0.2 1.1 2.4 10.2 1.1
0 0 0.7 1.2 2.1 1.4 2
1 1 0.4 1.3 2.2 6.8 1.5
I knew that to obtain normal (Pearson's) correlation/ covariance matrix, we can use:

corr x1 x2 x3 x4 x5 x6 x7
matrix r = r(C)

But for a robust correlation/ covariance matrix, which commands can be used to calculate this?

Thank you in advance

Best regards,

Anh
