Libraries.Compute.Statistics.Inputs.FactorInput Documentation
There are many ways in which a statistical test, transform, or calculation could potentially get data from a DataFrame. The Inputs package lists any of these ways. FactorInput specifically is stating that a particular class expects the data to be dummy coded. This means that we are adding a set of columns that indicate group values to be used as a factor. Effectively this means a dependent variable is coded as a column with all groups together and the factor columns indicate levels of an independent variable.

AddFactor(integer column)
This action adds a value to the end of the input.
Parameters
Compare(Libraries.Language.Object object)
This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.
Example Code
Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)
Parameters
- Libraries.Language.Object: The object to compare to.
Return
integer: The Compare result, Smaller, Equal, or Larger.
EmptyFactors()
This action empty's the list, clearing out all of the items contained within it.
Equals(Libraries.Language.Object object)
This action determines if two objects are equal based on their hash code values.
Example Code
use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(t)
Parameters
- Libraries.Language.Object: The to be compared.
Return
boolean: True if the hash codes are equal and false if they are not equal.
GetFactor(integer index)
This action gets the item at a given location in an array.
Parameters
Return
integer: The item at the given location.
GetFactorIterator()
This action gets an iterator for the object and returns that iterator.
Return
Libraries.Containers.Iterator: Returns the iterator for an object.
GetFactorSize()
This action gets the size of the array.
Return
integer:
GetHashCode()
This action gets the hash code for an object.
Example Code
Object o
integer hash = o:GetHashCode()
Return
integer: The integer hash code of the object.
IsEmptyFactors()
This action returns a boolean value, true if the container is empty and false if it contains any items.
Return
boolean: Returns true when the container is empty and false when it is not.
RemoveFactor(integer column)
This action removes the first occurrence of an item that is found in the Addable object.
Parameters
Return
boolean: Returns true if the item was removed and false if it was not removed.
RemoveFactorAt(integer index)
This action removes an item from an indexed object and returns that item.
