givitiCalibrationBeltTable

A <code>givitiCalibrationBelt</code> object, to be generated with
the function <code>givitiCalibrationBelt</code>.

Optional. A list with four character elements named
<code>overBisString</code>,<code>underBisString</code>,<code>confLevelString</code>,
<code>neverString</code>. The four strings of the list are printed instead of the
texts "Over the bisector"/"Under the bisector"/"Confidence level"/"NEVER"
in the table reporting the intersections of the calibration belt with
the bisector.

tableStrings

A vector containing the code of the
gray levels used in the plot of the calibration belt.

grayLevels

Numeric vectors of length 2, giving the
x and y coordinates ranges. Default values are <code>c(0,1)</code>.

xlim,ylim


<code>givitiCalibrationBeltTable</code> prints on the graphical area of the calibration
 belt plot the table that summarizes the significant deviations from the
 line of perfect calibration (i.e. the bisector of the I quadrant).


Functions to assess the calibration of logistic regression models with the GiViTI (Gruppo Italiano per la Valutazione degli interventi in Terapia Intensiva, Italian Group for the Evaluation of the Interventions in Intensive Care Units - see <http://www.giviti.marionegri.it/>) approach. The approach consists in a graphical tool, namely the GiViTI calibration belt, and in the associated statistical test. These tools can be used both to evaluate the internal calibration (i.e. the goodness of fit) and to assess the validity of an externally developed model.
