S3 class for primary event censored distribution computation

Usage

new_pcens(
  pdist,
  dprimary,
  dprimary_args,
  pdist_name = NULL,
  dprimary_name = NULL,
  ...
)

Arguments

pdist

Distribution function (CDF)

dprimary

Function to generate the probability density function (PDF) of primary event times. This function should take a value x and a pwindow parameter, and return a probability density. It should be normalized to integrate to 1 over [0, pwindow]. Defaults to a uniform distribution over [0, pwindow]. Users can provide custom functions or use helper functions like dexpgrowth for an exponential growth distribution. See primary_dists.R for examples.

dprimary_args

List of additional arguments to be passed to dprimary. For example, when using dexpgrowth, you would pass list(min = 0, max = pwindow, r = 0.2) to set the minimum, maximum, and rate parameters

pdist_name

A string specifying the name of the delay distribution function. If NULL, the function name is extracted using .extract_function_name(). Used to determine if a analytical solution exists for the primary censored distribution. Must be set if pdist is passed a pre-assigned variable rather than a function name.

dprimary_name

A string specifying the name of the primary event distribution function. If NULL, the function name is extracted using .extract_function_name(). Used to determine if a analytical solution exists for the primary censored distribution. Must be set if dprimary is passed a pre-assigned variable rather than a function name.

Additional arguments to be passed to pdist

Value

An object of class pcens_{pdist_name}_{dprimary_name}. This contains the primary event distribution, the delay distribution, the delay distribution arguments, and any additional arguments. It can be used with the pcens_cdf() function to compute the primary event censored cdf.
