    • getValueAt

      public double getValueAt​(double specificity) throws org.apache.commons.math.MathException
      Description copied from interface: ROC
      Returns the sensitivity at a given 1-specificity, i.e., 1-type 2 error, the number of true healthy for a given type 1 error, the number of false healthy.
      Specified by:
      getValueAt in interface ROC
      Parameters:
      specificity - the specificity (0.1 is 10%)
      Returns:
      the sensitivity at the given specificity (0.1 is 10%)
      Throws:
      org.apache.commons.math.MathException - if a MathException occurs
    • getSpecificityAt

      public double getSpecificityAt​(double sensitivity) throws org.apache.commons.math.MathException
      Description copied from interface: ROC
      Returns the 1-specificity at a given sensitivity.
      Specified by:
      getSpecificityAt in interface ROC
      Parameters:
      sensitivity - the sensitivity (0.1 is 10%)
      Returns:
      the corresponding 1-specificity (0.1 is 10%)
      Throws:
      org.apache.commons.math.MathException - if a MathException occurs
    • getxYValues

      public double[][] getxYValues() throws org.apache.commons.math.MathException
      Description copied from interface: ROC
      Returns xy values to draw the curve.
      Specified by:
      getxYValues in interface ROC
      Returns:
      xy values to draw the curve
      Throws:
      org.apache.commons.math.MathException - if a MathException occurs
    • getAuc

      public double getAuc() throws org.apache.commons.math.MathException
      Description copied from interface: ROC
      Returns an estimation of the area under the curve.
      Specified by:
      getAuc in interface ROC
      Returns:
      an estimation of the area under the curve
      Throws:
      org.apache.commons.math.MathException - if a MathException occurs
