MicroStrategy ONE
Chi-square distribution
Returns the right-tailed chi-squared distribution of the degrees of freedom, where the probability density function is given by
Where:
is the degree of freedom
is the gamma function
The chi-squared distribution is associated with a chi-squared test. A chi-squared test is used to compare observed values against expected ones. It determines the validity of a hypothesis, such as the prediction that the next generation of a certain plant hybrid will exhibit a specific combination of colors.
Syntax
Where:
x is a non-negative decimal value at which the distribution is evaluated.
df is an integer greater than or equal to one (>=1) indicating the number of degrees of freedom for the distribution.
Usage Notes
If df is not an integer, it is truncated
The following conditions are invalid:
- Either argument is nonnumeric
x < 0df < 1
