ggcalibrate | R Documentation |
ggcalibrate plots the stats::predicted events against the actual event rate
ggcalibrate(x1, x2 = NULL, y = NULL, n_knots = 5, ci_level = 0.95)
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). |
n_knots |
The curves are made by fitting a restricted cubic spline (rms package). The default 5-knots is usually enough. |
ci_level |
Confidence interval of the curve (default = 0.95). |
