Control Function for Logistic Regression Model Fitting
Source:R/control_logistic.R
control_logistic.Rd
This is an auxiliary function for controlling arguments for logistic regression models.
conf_level
refers to the confidence level used for the Odds Ratio CIs.
Arguments
- response_definition
(
string
)
the definition of what an event is in terms ofresponse
. This will be used when fitting the logistic regression model on the left hand side of the formula. Note that the evaluated expression should result in either a logical vector or a factor with 2 levels. By default this is just"response"
such that the original response variable is used and not modified further.- conf_level
(
proportion
)
confidence level of the interval.
Examples
# Standard options.
control_logistic()
#> $response_definition
#> [1] "response"
#>
#> $conf_level
#> [1] 0.95
#>
# Modify confidence level.
control_logistic(conf_level = 0.9)
#> $response_definition
#> [1] "response"
#>
#> $conf_level
#> [1] 0.9
#>
# Use a different response definition.
control_logistic(response_definition = "I(response %in% c('CR', 'PR'))")
#> $response_definition
#> [1] "I(response %in% c('CR', 'PR'))"
#>
#> $conf_level
#> [1] 0.95
