The data arise from a study of the quality of statements elicited from young children reported by Hutcheson et al. (1995). The variables are statement quality, child’s gender, age and maturity, how coherently the children gave their evidence, the delay between witnessing an incident and recounting it, the location of the interview (the child’s home, school, a formal interviewing room, or an interview room specially constructed for children), and whether or not the case proceeded to prosecution. Carry out a complete regression analysis on these data to see how statement quality depends on the other variables, including selection of the best subset of explanatory variables and examining residuals and other regression diagnostics. Pay careful attention to how the categorical explanatory variables with more than two categories are coded.
