ETABAR p-value

Dear All, Could anyone help me to interpret ETAbar p value? I have: TOT. NO. OF OBS RECS: 1486 TOT. NO. OF INDIVIDUALS: 213 ETABAR: -0.52E-02 -0.27E-01 -0.93E-01 P VAL.: 0.90E+00 0.24E+00 0.81E-04 ETA1 ETA2 ETA3 ETA1 4.08E-01 ETA2 2.26E-01 2.31E-01 ETA3 0.00E+00 0.00E+00 9.70E-01 which looks too low for me for eta3. I checked that p of abs(mean(eta)) > 0.093 is about 0.17 for normally distributed variable with SD=sqrt(0.97) and about 200 patients. > sum1 <- 0 > for(i in 1:1000000) if(abs(mean(rnorm(213,0,sqrt(0.97))))> 0.093) sum1 <- > sum1+1 > print(sum1/1000000) [1] 0.168624 How exactly this p-value is computed (NONMEM V) ? Thanks Leonid
