In SimNPH: Simulate Non-Proportional Hazards

Create a Function for Descriptive Statistics of a Dataset

Description

Create a Function for Descriptive Statistics of a Dataset

Usage

analyse_describe()

summarise_describe(name = NULL)

Arguments

name	name for the summarise function, appended to the name of the analysis method in the final results

Value

an analyse function that returns a list with the elements

• followup follow up time

• events table of events vs. treatment

• ice if column ice is present, table of intercurrent events, events, treatment

• subgroup if column subgroup is present, table of subgroup, events, treatment

A function that can be used in Summarise that returns a data frame with columns with means and standard deviations for every variable in the description.

Functions

• summarise_describe(): Summarise Descriptive Statistics

Examples

condition <- merge(
    assumptions_delayed_effect(),
    design_fixed_followup(),
    by=NULL
  ) |>
  head(1)
dat <- generate_delayed_effect(condition)
analyse_describe()(condition, dat)
condition <- merge(
  assumptions_delayed_effect(),
  design_fixed_followup(),
  by=NULL
) |>
  tail(4) |>
  head(1)

summarise_all <- create_summarise_function(
  describe=summarise_describe()
)

# runs simulations
sim_results <- runSimulation(
  design=condition,
  replications=100,
  generate=generate_delayed_effect,
  analyse=list(
    describe=analyse_describe()
  ),
  summarise = summarise_all
)

# study time is missing, since there was no admin. censoring
