IDAX.PCHISQ_H - High-tail cumulative chi-square distribution

The PCHISQ_H function returns the probability that a variable that follows the chi-square distribution is greater than x.

Syntax

IDAX.PCHISQ_H(DOUBLE x, INT8 df)

Parameter descriptions

x
Mandatory.
The value that is to be computed.
Min: 0.00000000001
Data type: DOUBLE
df
Mandatory.
The number of degrees of freedom.
If df is 0 or less, PCHISQ_H(x,df) is null for all x values.
Min: 1
Data type: INT8
PCHISQ_H(x,df)=1-PCHISQ(x,df) for all x values and df values.

Returned information

DOUBLE the cumulative probability distribution from x to plus infinity.
