My apologies, but there was an error in the NT_DIST function in the new release, Release 5.4, which also caused errors in the NT_NCP, NT_INV, T1_POWER, T2_POWER, T1_SIZE and T2_SIZE functions, as well as the Statistical Power and Sample Size data analysis tool for the t test options.
This error only occurred for certain combinations of parameters, but it is advised that you download the new version of the Real Statistics software (Rel 5.4.1) if you plan to use any of the above capabilities.
I apologize again for any inconvenience.
