QUEST stands for “Quick, Unbiased, Efficient Statistical Trees” and is a program for tree-structured classification. The algorithms are described in Loh and Shih (1997). The performance of QUEST compared with other classification methods can be found in Lim, Loh and Shih (2000). The main strengths of QUEST are unbiased variable selection and fast computational speed. In addition, it has options to perform CART-style exhaustive search and cost-complexity cross-validation pruning (Breiman, Friedman, Olshen and Stone, 1984). This version is coded in Fortran 90. The main changes since version 1.6 are
