Collectively, the chosen statistical analyses provide a pragmatic and parsimonious solution to the challenges posed by the data collected in this study. The analyses allowed clear conclusions about the major predictors of early and late communication skill in this sample and identified likely pathways through which early child, family, and educational environment variables have their influence.This article describes the major statistical analyses used in a large-scale follow-up study of prelingually deaf children implanted before 5 yrs of age. The data from this longitudinal project posed a number of challenges that required a compromise among statistical sophistication, ease of interpretation, consistency with analyses used following the initial wave of data collection, and attention to limited sample size and missing data. Primary analyses were based on principal components analysis to form composite measures of highly correlated variables followed by hierarchical multiple regression to determine the contribution of predictor sets ordered to reflect important causal assumptions and conceptual questions.
