- _A_r_g_u_m_e_n_t_s:
-
- x,q : vector of quantiles.
-
- p : vector of probabilites.
-
- n : number of observations.
-
- mean : vector of means.
-
- sd : vector of standard deviations.
-
- _D_e_s_c_r_i_p_t_i_o_n:
-
- These functions provide information about the normal
- distribution with mean equal to mean and standard devi-
- ation equal to sd. dnorm gives the density, pnorm
- gives the distribution function qnorm gives the quan-
- tile function and rnorm generates random deviates.
-
- If mean or sd are not specified they assume the default
- values of 0 and 1 respectively.
-
- The normal distribution has density
-
- f(x) = 1/(sqrt(2 pi) sigma)
- e^-((x - mu )^2/(2 sigma^2))
-
- where mu is the mean of the distribution and sigma the
- standard deviation.
