Question

Which of the following statement is normal distribution?

(a) dnorm(x, mean=0, sd=1, log = FALSE)

(b) pnorm(q, mean=0, sd=1, lower.tail = TRUE, log.p = FALSE)

(c) qnorm(p, mean=0, sd=1, lower.tail = TRUE, log.p = FALSE)

(d) rnorm(n, mean=0, sd=1)

The question was posed to me in unit test.

I want to ask this question from Commands in section Commands, Packages, Visualizing Data and Linear Regression of R Programming

Answer 1

Right choice is (a) dnorm(x, mean=0, sd=1, log = FALSE)

The best I can explain: d stands for density.
