piEst: Estimate population proportion and interval limits

In jgodet/utilitR: Lots of useful functions

Estimate population proportion and interval limits

Description

Estimate population proportion and interval limits from observede counts of succes and trials.

Usage

piEst(
  y = 12,
  n = 20,
  beta.priors = c(0.5, 0.5),
  credMass = 0.95,
  showPlot = FALSE,
  lateX = FALSE,
  ...
)

Arguments

y	counts of successes
n	counts of trials
beta.priors	vector of 2 non-negative parameters of the Beta prior distribution (shapes - by default Jeffrey's c(0.5,0.5))
credMass	mass of the HDI region
showPlot	if TRUE, show a graphical representation of Pi distribution
lateX	if TRUE, print lateX output

Value

Proportion estimates with HDI, CI (quantile c(.025,0.975)), and binomial CI (from binom.test)

Examples

piEst(y = 3, n = 12, showPlot = TRUE)
piEst(y = 3, n = 12, lateX = F)
