Conflicting results of cross sectional dependence testing in panel data (Pesaran CD, Frees, Friedman tests). Which result should I follow to assure most possible consistent and robust outcomes? Cannot trace what could cause such conflicting results, is there anything that needs to be addressed?
Please, let me know if there is any instructions, recommendations concerning this.

Thank you beforehand
