F-Test on two coefficients adding to 1

[Jad Tamimi]

Hello I ran a regression using this code:

reg BTC_r GSPTSE_r SSE_r GSPC_r

I'd like to use an F-test if the second and third coefficient add to one, as well as if the first coefficient is 0. What code can I use for this? Thanks.

test GSPTSE_r = 0, notest
test SSE_r + GSPC_r = 1, accum

much appreciated
