rho_A vs. composite realibility

[fgonzalezaleu]

I have SmartPLS version 3. After I ran the PLS, I when to review reliability and validity, finding three columns, Cronbach's alpha, rho_A, and composite reliability (three columns with different values).... Could you please tell me the difference between rho_A and composite reliability?

Thanks
Fernando
