The Decision curve

Description

ggdecision plots decision curves to assess the net benefit at different thresholds

ggdecision plots decision curves to assess the net benefit at different thresholds

Usage

ggdecision(x1, x2 = NULL, y = NULL)

ggdecision(x1, x2 = NULL, y = NULL)

Arguments

x1

Either a logistic regression fitted using glm (base package) or lrm (rms package) or calculated probabilities (eg through a logistic regression model) of the baseline model. Must be between 0 & 1

x2

Either a logistic regression fitted using glm (base package) or lrm (rms package) or calculated probabilities (eg through a logistic regression model) of the new (alternative) model. Must be between 0 & 1

y

Binary of outcome of interest. Must be 0 or 1 (if fitted models are provided this is extracted from the fit which for an rms fit must have x = TRUE, y = TRUE).

Value

a ggplot

a ggplot
