Inherited methods

DesignPrior$create()

`SourcePosteriorDesignPrior$new()`

Initializes a new instance of SourcePosteriorDesignPrior.

Usage

SourcePosteriorDesignPrior$new(
  source_data,
  case_study_config,
  simulation_config,
  mcmc_config = NULL
)

Arguments

source_data: The source data object.
case_study_config: Case study configuration
simulation_config: Simulation configuration
mcmc_config: MCMC configuration

`SourcePosteriorDesignPrior$sample()`

Samples from the source posterior design prior.

Usage

SourcePosteriorDesignPrior$sample(n_samples)

Arguments

n_samples: The number of samples to generate.

`SourcePosteriorDesignPrior$cdf()`

Computes the cumulative distribution function (CDF) of the source posterior design prior.

Usage

SourcePosteriorDesignPrior$cdf(x)

Arguments

x: The value at which to evaluate the CDF.

`SourcePosteriorDesignPrior$given_control_rate()`

The source posterior given the target control rate

Under a binomial likelihood the source posterior is independent Beta posteriors on the two arms' response rates, so given the control rate the effect is the treatment rate, from its source posterior, less that rate. Otherwise the inherited truncation applies.

Usage

SourcePosteriorDesignPrior$given_control_rate(control_rate)

Arguments

control_rate: The target control rate.

Returns

A FunctionalDesignPrior.

`SourcePosteriorDesignPrior$pdf()`

Computes the cumulative distribution function (PDF) of the source posterior design prior.

Usage

SourcePosteriorDesignPrior$pdf(x)

Arguments

x: The value at which to evaluate the PDF.

`SourcePosteriorDesignPrior$clone()`

The objects of this class are cloneable with this method.

Usage

SourcePosteriorDesignPrior$clone(deep = FALSE)

Arguments

deep: Whether to make a deep clone.
