Chi-squared distribution

Definition
AI-generated

Sum of squared standard normals—reference for Pearson tests and many LRTs when df fixed.

Why it matters in GWAS

Statistical concepts underpin GWAS significance, effect estimation, relatedness random effects, multiple testing, fine-mapping priors, and post-GWAS multivariate methods.

Example usage

"Under the null, the test statistic was compared to a chi-squared distribution to compute p-values."
