MeasurementScale Enumeration

Specifies the measurement scale explicitly assigned to a data frame column.

Definition

Namespace: Numerics.NET.DataAnalysis.Schema
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 10.8.0
C# 
public enum MeasurementScale

Remarks

The measurement scale is semantic metadata supplied by the caller. It is not inferred from the column element type. For example, numeric columns may validly be marked as nominal or ordinal when that reflects their meaning.

The assigned scale is independent of vector representation. Columns backed by categorical vectors may also validly use interval or ratio scales when the represented category values have that meaning.

Members

Nominal1 Values identify unordered categories.
Ordinal2 Values identify ordered categories.
Interval3 Values support ordered differences, but not a meaningful absolute zero for ratios.
Ratio4 Values support ordered differences and ratios relative to a meaningful absolute zero.
