How quickly can CART generate results?
A14. CART’s efficient algorithm generates results much faster than other methods, such as neural nets. On industry-standard servers, CART models based on 300,000 records and 1,000 variables can be generated in less than an hour. More typical problems involving 100,000 records and 450 variables run in approximately 10 minutes, while 100 variables and one million records can be run in less than 30 minutes. Exploratory analyses based on extracts from a large database can be conducted even faster; for example, a sample of 30,000 records with 100 selected input variables can be explored in less than five minutes.
