get_omega | R Documentation |
Extract variability parameter estimates from a NONMEM output object.
get_omega(x, output = "est", sigdig = 6, sep = "-", est.step = NULL)
x |
A NONMEM output object generated using |
output |
A flag specifying the matrix or matrices to be output. Valid flag values are |
sigdig |
Specifies the number of significant digits to be provided (default=6). |
sep |
Specifies the separator character to use for 95% confidence intervals (default="-"). |
est.step |
Specifies which estimation step to return parameters from (default is the last). |
Output options are as follows:
est returns the estimated OMEGA
variance-covariance matrix.
se returns the standard errors for the estimated OMEGA
variance-covariance matrix.
rse returns the relative standard errors for the estimated OMEGA
variance-covariance matrix (se/est*100
).
cor returns the correlation matrix matrix.
cse returns the standard errors for the correlation matrix.
95ci returns the asymptotic 95% confidence intervals for the elements of the OMEGA
variance-covariance matrix (est +/- 1.96*se
).
all returns all available OMEGA
matrices.
A symmetrical matrix, or a list of symmetrical matrices if all
is specified.
