-------- Original Message -------- Subject: pnorm instead of pt Date: Wed, 25 Nov 2009 15:57:40 -0800 (PST) From: Samuel Okoye <[email protected]> To: [email protected] Dear all, I have got z-score data and I would like to apply a t-test for between to groups! Can I use 2*(1-pnorm(abs(teststat))) instead of 2*(1-pt(abs(teststat),df=DF)) to compute the p-value? I have got also outliers in the z-scored data, is this OK? Many thanks in advance, Samuel -- Replies will be sent to the list. For more information visit http://www.morphometrics.org
