two methods for regression, two different results
Please forgive a straight stats question, and the informal notation.
let us say we wish to perform a liner regression:
y=b0 + b1*x + b2*z
There are two ways this can be done, the usual way, as a single
regression,
fit1<-lm(y~x+z)
or by doing two regressions. In the first regression we could have y as
the dependent variable and x as the independent variable
fit2<-lm(y~x).
The second
