Re: [R] About lm(y~1)

2014-04-28 Thread Rui Barradas 

Hello,

That will compute a "fit" with coefficient equal to mean(y) and std 
error equal to sd(y)/sqrt(length(y))


Hope this helps,

Dear list,
Reading a function I found this:

lm ( y ~ 1 )

I know that Y ~ -1 + A  is a straight-line with no y-intercept; that is, a
fit forced through (0,0). But I never saw the first example. Any tip?

Thanks in advance!
