A re-weighted strategy is introduced to find the robust trimmed subset that does not include outliers. Simultaneously, by maximizing the trimmed likelihood(More)
A new diterpenoid, 14β-hydroxy-3-oxo-ent-kaur-16-ene (1), and a new nor-lignan, 8S-( - )-8-(4-hydroxy-3-methoxybenzoyl)-dihydrofuran-8(8'H)-one (4), along with five known compounds were isolated from the twigs and leaves of Croton kongensis Gagnep.
