1. tetrachoric correlation

In statistics, polychoric correlation is a technique for estimating the correlation between two hypothesised normally distributed continuous latent variables, from two observed ordinal variables. Tetrachoric correlation is a special case of the polychoric correlation applicable when both observed variables are dichotomous. These names derive from the polychoric and tetrachoric series which are used for estimation of these correlations.

1. tetrachoric correlation

Tetrachoric correlation is a statistical method used to estimate the correlation between two dichotomous, or binary, variables. This method assumes that the variables are both reflective underlying continuous variables and are then dichotomized. The correlation estimates what the Pearson correlation between these continuous variables would be. It is often used in psychological and sociological research where dichotomous responses (e.g., true/false or agree/disagree answers) are used to measure underlying attitudes or attributes.
