Is there a R command for testing the difference of two liear regressions?
Hi al,
I am looking for a R command to test the difference of two linear
regressoon betas.
Lets say I have data x1, x2...x(n+1).
beta1 is obtained from regressing x1 to xn onto 1 to n.
beta2 is obtained from regressing x2 to x(n+1) onto 1 to n.
Is there a way in R to test whether beta1 and beta2 are statistically
different?
Thanks a lot!

I am trying to create a frequency distribution and I am a bit confused.
Here are the commands I have entered:
> data <- read.csv(file="40609_sortedfinal.csv",head=TRUE,sep=",")
> NumberOfActionsByStatus = data$STATUS
> NumberOfActionsByUser = data$ETS_LOGIN
> NumberOfBidOffer = data$BID_OFFER
> NumberOfActionsByUser.freq = table(NumberOfActionsByUser)
