-- associator_options
CheckAssociator reports on the following:
weka.associations.AbstractAssociatorTest
uses this
class to test all the associators. Any changes here, have to be
checked in that abstract test class, too.
Valid options are:
-D Turn on debugging output.
-S Silent mode - prints nothing to stdout.
-N <num> The number of instances in the datasets (default 20).
-nominal <num> The number of nominal attributes (default 2).
-nominal-values <num> The number of values for nominal attributes (default 1).
-numeric <num> The number of numeric attributes (default 1).
-string <num> The number of string attributes (default 1).
-date <num> The number of date attributes (default 1).
-relational <num> The number of relational attributes (default 1).
-num-instances-relational <num> The number of instances in relational/bag attributes (default 10).
-words <comma-separated-list> The words to use in string attributes.
-word-separators <chars> The word separators to use in string attributes.
-W Full name of the associator analysed. eg: weka.associations.Apriori (default weka.associations.Apriori)
Options specific to associator weka.associations.Apriori:
-N <required number of rules output> The required number of rules. (default = 10)
-T <0=confidence | 1=lift | 2=leverage | 3=Conviction> The metric type by which to rank rules. (default = confidence)
-C <minimum metric score of a rule> The minimum confidence of a rule. (default = 0.9)
-D <delta for minimum support> The delta by which the minimum support is decreased in each iteration. (default = 0.05)
-U <upper bound for minimum support> Upper bound for minimum support. (default = 1.0)
-M <lower bound for minimum support> The lower bound for the minimum support. (default = 0.1)
-S <significance level> If used, rules are tested for significance at the given level. Slower. (default = no significance testing)
-I If set the itemsets found are also output. (default = no)
-R Remove columns that contain all missing values (default = no)
-V Report progress iteratively. (default = no)
-A If set class association rules are mined. (default = no)
-c <the class index> The class index. (default = last)Options after -- are passed to the designated associator.
