Normal Outcome Distribution

Normal Outcome Distribution

Usage

outcome_cont_normal(
  continuous_var,
  baseline_prior,
  std_dev_prior,
  weight_var = ""
)

Arguments

continuous_var

character. Name of continuous outcome variable in the model matrix

baseline_prior

Prior. Object of class Prior specifying prior distribution for the baseline outcome. See Details for more information.

std_dev_prior

Prior. Object of class Prior specifying prior distribution for the standard deviation of the outcome distribution (i.e. "sigma").

weight_var

character. Optional name of variable in model matrix for weighting the log likelihood.

Value

Object of class OutcomeContinuousNormal.

Details

Baseline Prior

The baseline_prior argument specifies the prior distribution for the intercept of the linear model. The interpretation of the baseline_prior differs slightly between borrowing methods selected.

• Dynamic borrowing using borrowing_hierarchical_commensurate(): the baseline_prior for Bayesian Dynamic Borrowing refers to the intercept of the external control arm.

• Full borrowing or No borrowing using borrowing_full() or borrowing_none(): the baseline_prior for these borrowing methods refers to the intercept for the internal control arm.
