Glass Identification Database
Description
A data frame with 214 observations, where the problem is to predict the type
of glass in terms of their oxide content (i.e. Na, Fe, K, etc). The study of
classification of types of glass was motivated by criminological
investigation. At the scene of the crime, the glass left can be used as
evidence... if it is correctly identified!
Format
A data frame with 214 observations on the following 11 variables.
- Id
Id number.
- RI
Refractive index.
- Na
Sodium (unit measurement: weight percent in corresponding oxide,
as are attributes 4-10).
- Mg
Magnesium.
- Al
Aluminum.
- Si
Silicon.
- K
Potassium.
- Ca
Calcium.
- Ba
Barium.
- Fe
Iron.
- Type
Type of glass: (class
