Why I get high observation when I generate data from t-distribution in R I want to generate 200 samples from t-distribution with the degree of freedom=1 and sample size is 10 and in R
I use this code
set.seed(1234)
B <- matrix(rt(10*200, 1), 200)

But when I see the sample number 167 (B[167,]) I found this high number 602.1691029
And this strange thing in the t-distribution. What is wrong here?

Number 135 is even larger.
I guess the problem comes from the fact you're using df = 1, which looks odd. Because the uncertainty is just too large with one observation..
You won't get these large numbers starting at e.g. df = 5.
