Hi Nils,
I would say, pnorm is faster and has a higher precision.

you can use the `...' argument of integrate, e.g.,
integrate(dnorm, 0, 1)
integrate(dnorm, 0, 1, mean = 0.1)
integrate(dnorm, 0, 1, mean = 0.1, sd = 1.2)
look

BUT what can I do for dynamic m and sd?
I want something like integrate(dnorm(,0.6,0.15),0,1), with the first
dnorm parameter open for the
integration but fixed m and sd.
integrate(function(x)dnorm(x,0.1,1.2), 0, 1)
is a way of fixing additional
Hi everyone,
I am new to R, but it's really great and helped me a lot!
But now I have 2 questions. It would be great, if someone can help me:
1. I want to integrate a normal distribution, given a median and sd.
The integrate function works great BUT the first argument has to be a
function
so

look at ?integrate for more info.
I hope it helps.

Hi,
why don't you use pnorm?
E.g.,
pnorm(1, mean = 0.1, sd = 1.2) - pnorm(0, mean = 0.1, sd = 1.2)

Thank you,
both work fine. Why is pnorm to prefer?
