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; k; 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
Semantic
- CHISQINV(p; k) returns the value x, such that CHISQDIST(x; k;TRUE()) = p.
Example
CHISQINV(0.5724; 3)
- returns approximately 2.
