Chi-squared distribution
Summary
The chi-squared distribution with degrees of freedom is the law of a sum of the squares of independent standard normal random variables. It is central in tests and confidence intervals for variances. The node chi-squared distribution gives the precise definition.
What this node needs for W2
- edge instance_of in: at least two examples (0 of 2)
- edge not_instance_of in: at least one non-example (0 of 1)
- edge specializes both: the more general notions and the special cases (0 of 1)
The writing levels say how complete the text of a node is. They do not measure its truth.
