power_curve {PUMP}

Obtain a power curve for a range of sample size or MDES values

Description

This is used to see how power changes as a function of sample size or MDES. It takes a fit pumpresult and calculates a power curve based on that scenario coupled with a passed range of values to make the curve over.

Usage

power_curve(
  x,
  all = FALSE,
  low = NULL,
  high = NULL,
  grid.size = 5,
  tnum = 2000
)

Arguments

x

a pumpresult object.

all

logical; if TRUE, merge in the search path from the original search.

low

scalar; low range for curve.

high

scalar; high range for the curve.

grid.size

scalar; number of points to calculate power for.

tnum

scalar; number of iterations to calculate power at each grid point.

Value

data.frame of power results.
