List of precision() Examples

Examples of precision()

de.lmu.ifi.dbs.elki.evaluation.clustering.BCubed.precision()
Get the BCubed Precision (first clustering) (normalized, 0 = unequal) @return BCubed Precision
de.lmu.ifi.dbs.elki.evaluation.clustering.PairCounting.precision()
Computes the pair-counting precision. @return pair-counting precision
java.math.BigDecimal.precision()
Returns the precision of this {@code BigDecimal}. (The precision is the number of digits in the unscaled value.)
The precision of a zero value is 1. @return the precision of this {@code BigDecimal}. @since 1.5
javax.persistence.Column.precision()
javax.persistence.MapKeyColumn.precision()
org.apache.camel.dataformat.bindy.annotation.DataField.precision()
org.apache.camel.dataformat.bindy.annotation.KeyValuePairField.precision()
org.apache.hadoop.hive.common.type.HiveDecimal.precision()
org.apache.hadoop.hive.serde2.typeinfo.DecimalTypeInfo.precision()
weka.classifiers.Evaluation.precision()
Calculate the precision with respect to a particular class. This is defined as
```
 correctly classified positives ------------------------------ total predicted as positive 
```
@param classIndex the index of the class to consider as "positive" @return the precision
