Multilevel model predicting the difference of diary and Followback reported number of drinks

Variable	B (SE)
Average over days intercept, β0	−0.15 (0.11)
Female gender, γ01	0.22 (0.10)*
Average past drinking quantity, γ02	−0.04 (0.01)**
Fraternity affiliation, γ03	0.12 (0.10)
Person mean drinks across days, γ04	0.15 (0.05)**
Average fluctuations in daily total drinks, β1
Intercept, γ10	0.46 (0.04)***
Fraternity affiliation, γ11	0.17 (0.07)*
Average fluctuations with weekend, β2
Intercept, γ20	−0.19 (0.06)**
Fraternity affiliation, γ21	−0.82 (0.19)***
Average fluctuations with Halloween, β3
Intercept, γ30	−1.64(0.26)***
Average fluctuations by week of study, β4
Intercept, γ40	0.03 (0.03)

Notes: n = 176 students on N = 4,579 person days.

Level 1: Y = β₀ + β₁ (daily drinks) + β₂ (weekend) + β₃ (Halloween) + β₄ (week of study) + r_it

Level 2: β₀ = γ₀₀ + γ₀₁ (gender) + γ₀₂ (average drinking past month) + γ₀₃ (fraternity affiliation) + γ₀₄ (person mean drinks) + U₀

β₁ = γ₁₀ + γ₁₁ (fraternity affiliation)

β₂ = γ₂₀ + γ₂₁ (fraternity affiliation)

β₃ = γ₃₀

β₄ = γ₄₀
