statsmodels.distributions.copula.api.StudentTCopula.fit_corr_param¶ StudentTCopula.fit_corr_param(data)¶ Copula correlation parameter using Kendall’s tau of sample data. Parameters:¶ data : array_like¶Sample data used to fit theta using Kendall’s tau. Returns:¶ corr_param – Correlation parameter of the copula, theta in Archimedean and pearson correlation in elliptical. If k_dim > 2, then average tau is used. Return type:¶ float
