Libraries.Compute.Statistics.Inputs.FactorInput

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.

This action adds a value to the end of the input.

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)

This action empty's the list, clearing out all of the items contained within it.

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)

This action gets the item at a given location in an array.

This action gets an iterator for the object and returns that iterator.

This action gets the size of the array.

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

This action returns a boolean value, true if the container is empty and false if it contains any items.

This action removes the first occurrence of an item that is found in the Addable object.

This action removes an item from an indexed object and returns that item.
