Methods for simple_eiv objects

Methods defined for objects returned from the error-in-variables models (e.g., dem_reg).

Usage

# S3 method for class 'simple_eiv'
print(x, ...)

# S3 method for class 'simple_eiv'
plot(x, x_name = "x", y_name = "y", show_joint = TRUE, ...)

# S3 method for class 'simple_eiv'
check(x)

plot_joint(object, ...)

# S3 method for class 'simple_eiv'
plot_joint(
  object,
  ideal_slope = 1,
  ideal_intercept = 0,
  show_intervals = TRUE,
  ...
)

# S3 method for class 'simple_eiv'
vcov(object, ...)

# S3 method for class 'simple_eiv'
coef(object, ...)

Arguments

x

object of class simple_eiv from the dem_reg function.

...

further arguments passed through, see description of return value. for details. agree_test.

x_name

Name/label for x values (first measurement)

y_name

Name/label for y values (second measurement)

show_joint

Logical. If TRUE and joint region computed, shows joint region status in subtitle.

object

object of class simple_eiv for plot_joint method

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.

Value

print

Prints short summary of the error-in-variables (e.g., Deming) regression model.

plot

Returns a plot of the deming regression line, the line-of-identity, and the raw data.

check

Returns plots of the optimized residuals.

plot_joint

Returns a plot of the joint confidence region in parameter space.
