fixcut_con {BioPred}

Fixed Cutoff Analysis for Individual Biomarker Associated with Continuous Outcome

Description

This function conducts fixed cutoff analysis for individual biomarker associated with continuous outcome variables.

Usage

fixcut_con(
  yvar,
  xvar,
  dir,
  cutoffs,
  data,
  method = "t.test",
  yvar.display = yvar,
  xvar.display = xvar,
  vert.x = FALSE
)

Arguments

yvar

Continuous response variable name.

xvar

Biomarker name.

dir

Cutoff direction for the desired subgroup. Options are ">", ">=", "<", or "<=".

cutoffs

A vector of candidate cutoffs.

data

The dataset containing the variables.

method

Method for cutoff selection. Currently only supports "t.test". - "t.test": Minimizes the t-test p-value.

yvar.display

Display name of the response variable.

xvar.display

Display name of the predictor variable.

vert.x

Whether to display the cutoff in a 90-degree angle when plotting (saves space).

Value

A list containing statistical summaries, selected cutoff statistics, selected cutoff value, group statistics, and a ggplot object for visualization.
