dear statalisters -
i'm resending this with more detail in hopes of any help-
i have a panel time-series data set, i=id, t=time
i am trying to do a regression of two indep vars on one dep var. the basic
form will be:
Zi = aXi + bYi + ci
however, X and Y were measured with two different instruments, whose
identity is not in the database. instrument 2 has a fixed ofset from
instruemtn 2, such that
X2 = X1+10 and Y2 = Y1+10
for all t within i, the measurements were made with the same instrument
i would like to fit the first general equation, and determine whether each
id best fits instrument 1 or 2.
i have read switchr but i don't think this fits.
any help is appreciated,
thank you
george hoffman
