Intercept in model formulae.
Hi,
I'm trying to create a linear model for a dataset that has a breakpoint e.g.
# dummy dataset
x <- 1:20
y <- c(1:10,seq(10.5,15,0.5))
plot(x,y)
I've modelled this using the following formula:
temp <- lm(y ~ x*(x<=10)+x*(x>10))
I want to be able to omit the intercept (i.e. force the line through
zero) from the first of these segments (x<=10) so that I'm only
