Distribution
This category contains probability density functions, and
both cumulative probability functions and their inverses,
for the common probability distributions. These
distributions include the Normal, Binomial, Chi-square,
Fisher, Poisson, and Student's t distributions.
normald
Normal probability density function. Computes the
probability density at the value x, given the mean,
μ
and
standard deviation,
σ
of a normal distribution. If only a
single value (x) is supplied, assumes
μ
=0 and
σ
=1.
normald
([
μ
,
σ
,] x)
Example:
normald
(0.5)
and normald
(0, 1, 0.5) both return
0.352065326765
.
normald_cdf
Cumulative normal distribution function. Returns the
lower-tail probability of the normal probability density
function for the value x, given the mean,
μ
and standard
deviation,
σ
of a normal distribution. If only a single value
(x) is supplied, assumes
μ
=0 and
σ
=1.
normald_cdf
([
μ
,
σ
,] x)
Example:
normald_cdf
(0, 1, 2) returns
0.97724986805
