Description
This function is used to estimate theta assuming the gold standard biomarker is used.
Further the distribution of the biomarker is assumed to be normaly distributed with
a given mean and variance.
Usage
1
thetama(mydat)
Arguments
mydat
A data frame with the outcome variable and exposure variables
Details
This metric measure the decrease in the expected proportion of events that were avoided
as a result of using the biomarker guided treatment. However the biomarker observed is the
modified asssay rather than the gold standard assay. To reduce the computational time, a raoblackwelization
method conditioning over the sufficient statistics was used.
Value
A value in the range of 0-1.

# Let the data is stored in an object named mydat
# Let dpar the parmaters of the normally distributed biomarker
