Simple Power Simulation

A basic example of a power simulation function.

Usage

sim_power(
  design = list(trend = -0.03, n_year = 12, n_sample = 20),
  n_sim = 100,
  intercept = 2,
  sigma_error = 0.1
)

Arguments

design

A named list with design parameters:

• trend: The true trend parameter

• n_year: Number of years

• n_sample: Number of samples per year

n_sim

Integer. Number of simulations.

intercept

Numeric. Intercept of the model.

sigma_error

Numeric. Standard deviation of the error term.

Value

A data frame with columns:

• p: P-values from simulations

• trend: Estimated trends

Details

Simulates data under a simple model and returns p-values.

Examples

if (FALSE) { # \dontrun{
sim_power(
  design = list(trend = -0.03, n_year = 12, n_sample = 20),
  n_sim = 10
)
} # }
