moecalc: Margin of Error Calculation

Description

Computes the margin of error for various objects.

Usage

moecalc(
  x,
  factorname = NULL,
  levelnames = NULL,
  coef.idx = NULL,
  est = NULL,
  ci = NULL,
  base = TRUE,
  basename = "base",
  conf.level = 1.96
)

Value

a moecalc object

Arguments

x

the object for which we compute margins of error

factorname

name of factor

levelnames

names of factor levels

coef.idx

index of coefficient to use

est

estimates

ci

confidence intervals

base

baseline

basename

name of baseline

conf.level

level of confidence to use

Details

If x is a model, must have factorname or coefficient index (coef.idx) If input factorname, will compute ErrBars by factorname (for given model) If input coefficient index, will compute ErrBars simply by index only (even they are not factor) If x is ses.moecalc object, will compute ErrBars simply by given ses.moecalc object

Examples

fit <- lm(Sepal.Length ~ Species, data = iris)
(mc <- moecalc(fit, "Species"))
summary(mc)
plot(mc)
