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
