Limits() [3/5]

Limits::Limits	(	const VectorDouble &	bounds,
		bool	addFromZero = false
	)

Create the limits from a list of bounds. Intervals are delimited between two given bounds: [z_i, z_(i+1)[

Parameters

bounds	List of cutoffs used to create the limits. The number of limits is equal to the number of elements in the 'bounds' vector minus one.
addFromZero	When TRUE, add a class from 0 to bounds[0]

statistics()

VectorDouble Limits::statistics	(	Db *	db,
		const String &	name,
		int	optionStat = 1,
		bool	flagBelow = false,
		bool	flagAbove = false
	)

Calculate the statistics per Class

Parameters

db	Target Db
name	Name of the Target Variable
optionStat	1 for Mean; 2 for Proportions
flagBelow	When TRUE, add a class for samples below lowest bound
flagAbove	When TRUE, add a class for samples above highest bound

Returns

toCategory()

int Limits::toCategory	(	Db *	db,
		const String &	name = "",
		const NamingConvention &	namconv = NamingConvention("Category")
	)		const

toCategoryByAttribute()

int Limits::toCategoryByAttribute	(	Db *	db,
		int	iatt,
		const NamingConvention &	namconv
	)		const

toIndicator()

int Limits::toIndicator	(	Db *	db,
		const String &	name = "",
		int	OptionIndicator = 1,
		bool	flagBelow = false,
		bool	flagAbove = false,
		const NamingConvention &	namconv = NamingConvention("Indicator")
	)		const

Create indicators variables on the intervals defined by the limits for a given variable in a Db.
Note:

• If OptionIndicator is 1, the Db-class will contain the new indicator variables. There are as many new variables as they are classes. Each sample of the indicator variable for class 'iclass' is set to 1 if the sample belongs to this class or 0 otherwise.
• If OptionIndicator is 0, the Db-class will contain one variable such that each sample contains the average of the variable calculated over the samples whose value belong to this class.

Parameters

db	Db containing the variable to be discretized (from which the indicators are computed)
name	Name of the variable in the Db to be discretized.
OptionIndicator	When 1, the function assignes the indicator variables. When 0, the function assignes the average of the class.
flagBelow	When True, consider samples below lowest bound
flagAbove	When True, consider samples above highest bound
namconv	Naming convention

Returns

toIndicatorByAttribute()

int Limits::toIndicatorByAttribute	(	Db *	db,
		int	iatt,
		int	OptionIndicator = 1,
		bool	flagBelow = false,
		bool	flagAbove = false,
		const NamingConvention &	namconv = NamingConvention("Indicator")
	)		const
