Functions and commands
Density
Normal
Normal probability density function. Computes the
probability density at value
x
, given the mean,
and
standard deviation,
of a normal distribution. If only one
argument is supplied, it is taken as
x
, and the assumption is
that
=0 and
=1.
NORMALD([
,
,]
x
)
Example:
NORMALD(0.5)
and
NORMALD(0,1,0.5)
both return
0.352065326764.
T
Student’s t probability density function. Computes the
probability density of the Student's t-distribution at
x
, given
n
degrees of freedom.
STUDENT(n,x)
Example:
student(3,5.2)
returns
0.00366574413491.
probability density function. Computes the probability
density of the distribution at
x
, given
n
degrees of freedom.
CHISQUARE(n,x)
Example:
CHISQUARE(2,3.2)
returns
0.100948258997.
F
Fisher (or Fisher–Snedecor) probability density function.
Computes the probability density at the value
x
, given
numerator
n
and denominator
d
degrees of freedom.
FISHER(n,d,x)
Example:
FISHER(5,5,2)
returns
0.158080231095.
Binomial
Binomial probability density function. Computes the
probability of
k
successes out of
n
trials, each with a
probability of success of
p
. Returns Comb(n,k) if there is no
third argument. Note that
n
and
k
are integers with
.
BINOMIAL(n,k,p)
Example: Suppose you want to know the probability that just
6 heads would appear during 20 tosses of a fair coin.
BINOMIAL(20,6,0.5)
returns
0.03696441652002.
