CHISQDIST

Calculates values for a χ²-distribution.

Syntax

CHISQDIST(x; k; Cumulative)

x is a number.

k is the (positive integer) degrees of freedom for the χ²-distribution.

Cumulative is a logical value. In the case Cumulative=TRUE() the cumulative distribution function is used, in the case Cumulative=FALSE() the probability density function. This parameter is optional. It is set to TRUE() if missing.

Semantic

CHISQDIST(x; k; FALSE()) returns the probability density function for the χ²-distribution:

and

CHISQDIST(x; k; TRUE()) returns the left tail probability for the χ²-distribution:

and

Semantic with forced pictures

CHISQDIST(x; k; FALSE()) returns the probability density function for the χ²-distribution:

and

CHISQDIST(x; df; TRUE()) returns the left tail probability for the χ²-distribution:

and

Example

CHSQDIST(2.7;3;FALSE())

returns approximately 0.1699395239

CHSQDIST(2.7;3;TRUE())

returns approximately 0.5597727056

CHISQINV

Calculates the inverse of the CHISQDIST function.

Syntax

CHISQINV(p; k)

k is the (positive integer) degrees of freedom for the χ²-distribution.

p is the given probability, a number with 0 ≤ p < 1

Semantic

CHISQINV(p; k) returns the value x, such that CHISQDIST(x; k;TRUE()) is p.

Example

CHISQINV(0.5724; 3)

returns approximately 2.
