Visualizing Risk Prediction Models
Description
This is a package to visualize risk prediction models. For each
predictor, a color bar represents the contribution to the linear predictor or
latent variable. A conversion from the linear predictor to the estimated risk
or survival is also given. (Cumulative) contribution charts enable to visualize
how the estimated risk for one particular observation is obtained by the model.
Several options allow to choose different color maps, and to select the zero
level of the contributions. The package is able to deal with 'glm', 'coxph',
'mfp', 'multinom' and 'ksvm' objects. For 'ksvm' objects, the visualization
is not always exact. Functions providing tools to indicate the accuracy of the
approximation are provided in addition to the visualization.
