| PARAMETERS OMEGA SIGMA: CURRENT |

+--------------------------------------------------------------------+
MEANING: NONMEM read-only global variables
CONTEXT: PRED routine
USAGE:
USE ROCM_REAL, ONLY: OMEGA=>VARNF
GLOBAL DECLARATION:
USE SIZES, ONLY: LVR,DPSIZE
REAL(KIND=DPSIZE) :: VARNF(LVR,LVR)
DISCUSSION:
OMEGA
The current value of OMEGA being used.
The current value of SIGMA is also located in this array as follows:
SIGMA(I,J)=OMEGA(NETAS_+I,NETAS_+J)
NETAS_ is described in Parameter dimensions.
(See Parameter dimensions).
At run and problem initialization and at problem finalization use the
variables OMEGAF and SIGMAF.
(See Parameter values: Initial and Final).
Should not be used if an initial estimate is being computed.
When an initial estimate is being computed, the value is just that
found
at problem initialization (when ICALL=1).
EXAMPLE:
Compute individual weighted residuals using a slope-intercept residual
error model:
$ERROR
Y=F+EPS(1)+F*EPS(2)
IF (COMACT.GE.1) THEN
STD=SQRT(SIGMA(1)+F**2*SIGMA(2))
IWRES=(DV-F)/STD
ENDIF
