More Context Variables on Nasa93

Possible Context Variables for Datasets

• Cocomo81: Development mode
• Nasa93: Dev. center, flight-ground, category of application, year of development
• Desharnais: Development language
• Albrecht: None (all numeric attributes)

Previous results suggested that there is not a strong correlation between above context variables and selection. Further experiments for Nasa93 (flight-ground, category of application, year of development) point to a similar conclusion: Afore mentioned context variables do not have strong influence on selection.
