Control function for logistic regression model fitting

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.

control_logistic(response_definition = "response", conf_level = 0.95)

Arguments

response_definition

(string)
the definition of what an event is in terms of response. 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.

Value

A list of components with the same names as the arguments.

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
