Stata test relationship between coefficients

[Red Taho]

Hi,

Can anyone help me with the following? I am trying to test this relationship after estimating a linear regression: b_4<b_3<b_2<b_1<0. How can I do that in stata?

Thank you!

and especially look at the operators particularly "a." and "ar."

note that you don't really supply enough information for me to be sure that this is what you want so this is a guess
