How do I test against a simple null that two regressions coefficients are equal?
Hi there,
I run two regressions:
y = a1 + b1 * x + e1
y = a2 + b2 * z + e2
I want to test against the null hypothesis: b1 = b2. How do I design the test?
I think I can add two equations together and divide both sides by 2:
y = 0.5*(a1+a2) + 0.5*b1 * x + 0.5*b2 * z + e3, where e3 = 0.5*(e1 + e2).
or just y = a3 + 0.5*b1 * x + 0.5*b2 * z + e3
If I run this new regression, I can test against

Rails configuration for sessions
I''m trying to get the configuration done for sessions but I can''t seem
to find any documentation on how to do it beyond the merest of basics.
I would rather have something that would NOT persist a marshalled object
to the database since that''s just not something I want to do. I want to
be able to read the data for one.
But there''s really nothing to identify how that is done.
Or even identified in the Rai...
