Z-Prime (Z') and SSMD

Hello,

Is there a statistical shortcut in JMP to calculating Z-prime (Z') or SSMD (strictly standardized mean difference)? I'm searched around but I keep getting sent to trainings on Z-score.

Re: Z-Prime (Z') and SSMD

Hi @JB4 : I see no single JMP function for this, but it should be easy enough using functions for sample means and sample standard deviations (see links below).
