Description

[MTHlfNXTl PROB (NXTl:

UTPC

Upper-tail chi-square distribution.

Prefix. Takes the degrees of freedom

from level 2 and a real number (r) from

level 1, and returns the probability that

a random variable is greater than x.

IJTPF

UTPF

Upper-tail f distribution. Prefix. Takes

the numerator degrees of freedom from

level 3, the denominator degrees of

freedom from level 2, and a real number

(a;) from level 1, and returns the

probability that a Snedecor’s F random

variable is greater than x.

UTPN

Upper-tad normal distribution. Prefix.

Takes the mean from level 3, the

variance from level 2, and a real number

(r) from level 1, and returns the

probability that a normal random

variable is greater than x for a normal

distribution.

IJTPT

UTPT

Upper-tad t distribution. Prefix. Takes

the degrees of freedom from level 2 and

a real number (x) from level-1, and

returns the probability that the

Student’s t random variable is greater

than X.

HD I ST

NDIST

Normal distribution. Prefix. Takes the

mean from level 3, the variance from

level 2, and a real number (a;) from level

1, and returns the density function at x

for a normal distribution.

Note that, when used as an argument for these commands, the number

of degrees of freedom must be between 0 and 499. Also, in the

calculations, the degrees of freedom are rounded to the nearest integer.
