Good evening! Thanks for your answer, but I don't really understand how to use
vcov matrix for comarision of multiple regression line slopes...
I've read this theme about using t-test in slope comarision:

but how to use it in case o
Hi Антон,
my approach would be to use the estimated variance of the slope
estimator. For your regression models m1 and m2 you can enter
vcov(m1)
vcov(m2)
to get the variance-covariance matrix of m1 and m2. Then, assuming that
the slope estimator is normal, you compute the p-value for slope_theo
Hi all,
I need to test the significnce of difference between slopes of two regression
lines and regression line with theoretical line. I try to use Slope.test
function from emu package,
but an error occured...
