Libraries.Compute.Statistics.Calculations.InterQuartileRange Documentation

This class calculates the mean of a particular DataFrameColumn.

Example Code

use Libraries.Compute.Statistics.DataFrame
    use Libraries.Compute.Statistics.Calculations.InterQuartileRange

    //Load a comma separated file
    DataFrame frame
    frame:Load("Data.csv") 
    InterQuartileRange iqr
    DataFrameColumn column = frame:GetColumn(0)
    column:Calculate(iqr)
    number result = iqr:GetInterQuartileRange()
    output resu

Add(Libraries.Language.Types.Number value)If the calculation returns true from IsIterable, this is a Number object that was passed to the calculation.

Actions Documentation

Add(Libraries.Language.Object value)

If the calculation otherwise has no primitive type, it sends it to the column as a raw object. Columns might use this if they have custom type

Parameters

Add(Libraries.Language.Types.Integer value)

If the calculation returns true from IsIterable, this is an Integer object that was passed to the calculation. This may be undefined, which indicates that the column did not contain a value at this position in the colum

Parameters

Add(Libraries.Language.Types.Boolean value)

If the calculation returns true from IsIterable, this is a Boolean object that was passed to the calculation. This may be undefined, which indicates that the column did not contain a value at this position in the colum

Parameters

Add(Libraries.Language.Types.Number value)

If the calculation returns true from IsIterable, this is a Number object that was passed to the calculation. This may be undefined, which indicates that the column did not contain a value at this position in the colum

Parameters

Add(Libraries.Language.Types.Text value)

If the calculation returns true from IsIterable, this is a Text object that was passed to the calculation. This may be undefined, which indicates that the column did not contain a value at this position in the colum

Parameters

Calculate(Libraries.Compute.Statistics.DataFrameColumn column)

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 (smalle

Parameters

Return

integer: The Compare result, Smaller, Equal, or Larger.

Empty()

This Calculation can be re-used if the Empty action is called before passing it to another column. Otherwise, it retains its dat

End(Libraries.Compute.Statistics.DataFrameColumn column)

This action is called at the end of a calculatio

Parameters

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(

Parameters

Return

boolean: True if the hash codes are equal and false if they are not equal.

GetBottomMedian()

Returns the median in the bottom half of the column.

Return

number: the median in the bottom ha

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.

GetInterQuartileRange()

Returns the interquartile range, which is the top median - the bottom median.

Return

number: the interquartile rang

GetMaximum()

Returns the max value in the data set.

Return

number: the max val

GetMedian()

Returns the median for the column.

Return

number: the medi

GetMinimum()

Returns the min value in the data set.

Return

number: the min val

GetSize()

Returns the sample size for the column.

Return

integer: the sample si

GetTopMedian()

Returns the median in the top half of the column.

Return

number: the median in the top ha

IsIterable()

Return

boolean
