Confidence ellipse

Description

Confidence ellipse for two parameters of a fitted object

Usage

cell(x, ...)

## S3 method for class 'wald'
cell(
  obj,
  which.coef = 1:2,
  levels = 0.95,
  Scheffe = FALSE,
  dfn = 2,
  center.pch = 19,
  center.cex = 1.5,
  segments = 51,
  xlab,
  ylab,
  las = par("las"),
  col = palette()[2],
  lwd = 2,
  lty = 1,
  add = FALSE,
  ...
)

## Default S3 method:
cell(
  model,
  which.coef,
  levels = 0.95,
  Scheffe = FALSE,
  dfn = 2,
  center.pch = 19,
  center.cex = 1.5,
  segments = 51,
  xlab,
  ylab,
  las = par("las"),
  col = palette()[2],
  lwd = 2,
  lty = 1,
  add = FALSE,
  ...
)

Arguments

x	fitted object
...	other arguments passed to method
which.coef	(default 1:2) which parameters to estimate
levels	(default 0.95)
dfn	(default 2) degrees of freedom for Sheffe multiple test and confidence limits
Sheffe	logical (default FALSE)

Methods (by class)

• cell(wald): method for wald object

• cell(default): default method
