When and how do children develop knowledge of verb argument structure? Evidence from verb bias effects in a structural priming task (2015, background): “All factors were effect/sum coded (Wendorf, 2004), except for age in years, which was centred to reduce multi-collinearity (Neter, Wasserman, & Kutner, 1985).”
Statistical mediation analysis with a multicategorical independent variable. (2014, unknown): “For a discussion of various coding strategies, see Cohen et al. (2003), Davis (2010), Hardy (1993), Kaufman and Sweet (1974), Serlin and Levin (1985), Wendorf (2004), and West et al. (1996).”
Contrast Coding in Multiple Regression Analysis: Strengths, Weaknesses, and Utility of Popular Coding Structures (2021, methodology): “Completion is just as easy though, first group one is given a 1 in the first contrast with all other groups receiving a 0, in the second contrast group two receives a 1 with all other groups receiving a 0, and so forth (Wendorf, 2004).”
