#'
#' Dataset from a study by Carrillo et al. (2001), who assessed the extent to 
#' which the subscales of the NEO Personality Inventory (NEO-PI; Costa and 
#' McCrae 1985) could predict depressive symptomatology, as measured by the 
#' Beck Depression Inventory (BDI; Beck, Steer, and Carbin 1988). The NEO-PI 
#' assesses five major personality dimensions (Neuroticism, Extraversion, 
#' Openness to Experience, Agreeableness and Conscientiousness). Each of these
#' dimensions consist of six specific subtraits (facets). The NEO-PI and BDI 
#' were administered to 112 Spanish respondents. Respondents' age in years and 
#' sex were also recorded and included in the dataset.
