fitted.lod_lm: Extract lod_lm residuals

Description

Extracts fitted values from object of class "lod_lm".

Usage

# S3 method for lod_lm
fitted(object, ...)

Arguments

object

An object of class "lod_lm", usually, a result of a call to lod_lm

...

further arguments passed to or from other methods.

Value

Fitted values extracted from object as a named numeric vector.

Details

For subjects with covariates outside of limits of detection, when computing fitted values the values for these covariates are set according to method specified by argument fill_in_method in call to lod_lm.

Examples

# NOT RUN {
library(lodr)
## Using example dataset provided in lodr package: lod_data_ex
## 3 covariates: x1, x2, x3 with x2 and x3 subject to a lower limit of
## detection of 0

## nSamples set to 100 for computational speed/illustration purposes only.  
## At least 250 is recommended.  Same for boots=0; results in NAs returned for standard errors
 
fit <- lod_lm(data=lod_data_ex, frmla=y~x1+x2+x3, lod=c(0,0),
                  var_LOD=c("x2", "x3"), nSamples=100, boots=0)
