summary(object, ...)

## S3 method for class 'simple_eiv'
confint(object, parm, level = NULL, ...)

## S3 method for class 'simple_eiv'
plot(
  x,
  x_name = NULL,
  y_name = NULL,
  interval = c("none", "confidence"),
  level = NULL,
  n_points = 100,
  data = NULL,
  ...
)

## S3 method for class 'simple_eiv'
check(x, data = NULL, ...)

plot_joint(x, ...)

plot_joint(
  x,
  ideal_slope = 1,
  ideal_intercept = 0,
  show_intervals = TRUE,

coef(object, ...)

## S3 method for class 'simple_eiv'
fitted(object, type = c("y", "x", "both"), data = NULL, ...)

## S3 method for class 'simple_eiv'
residuals(object, type = c("optimized", "x", "y", "raw_y"), data = NULL, ...)

## S3 method for class 'simple_eiv'
predict(
  object,
  newdata = NULL,

Arguments

...	further arguments passed through.
formula	A simple_eiv object (for model.frame method)
data	Optional data frame. Required if model was fitted with model = FALSE and newdata is NULL.
na.action	Function for handling NA values (default: na.pass)
object, x	object of class simple_eiv from dem_reg or pb_reg function.
parm	A specification of which parameters are to be given confidence intervals, either a vector of numbers or a vector of names. If missing, all parameters are considered.
level	Confidence level for intervals (default uses the model's conf.level).
x_name	Name for x-axis label (optional).
y_name	Name for y-axis label (optional).
interval	Type of interval calculation. Can be "none" (default), or "confidence"
n_points	Number of points to use for drawing the joint confidence region (default = 100).
ideal_slope	The hypothesized slope value to test against (default = 1)
ideal_intercept	The hypothesized intercept value to test against (default = 0)
show_intervals	Logical. If TRUE, shows individual confidence intervals as well.
type	Type of residuals to return. Options are "optimized" (default), "x", "y", or "raw_y".
newdata	An optional data frame containing values of X at which to predict. If omitted, the fitted values are returned.
se.fit	Logical. If TRUE, standard errors of predictions are returned. Note: For Passing-Bablok regression without bootstrap, standard errors are not available and this argument is ignored with a warning.
