Equations for multilevel models

Model equations for Aim 1 analyses (whole sample)
Level 1:
S1 Outcome_ij = π_0i + π_1i(Weekend day_i)+ π_2i(WP Location_i)+ ε_ij
Level 2:
π_0i = γ₀₀ + γ₀₁(Gender_i) + γ₀₂(BP Location_i) + γ₀₃(BP Single_i) + γ₀₄(BP GCDR_i) + ζ_0i
π_1i = γ₁₀
π_2i = γ₂₀ + γ₂₁(BP Single_i)^* + γ₂₂(BP GCDR_i)^*
Model equations for Aim 2 analyses (subsample of students in an LDDR at Semester 1)
Level 1:
S2 Outcome_ij = π_0i + π_1i(Weekend day_i)+ π_2i(WP Location_i)+ ε_ij
Level 2:
π_0i = γ₀₀ + γ₀₁(Gender_i) + γ₀₂(BP Location_i) + γ₀₃(BP LDDR-Single_i) + γ₀₄(BP LDDR-same relationship_i) + ζ_0i
π_1i = γ₁₀
π_2i = γ₂₀ + γ₂₁(BP LDDR-Single_i)^* + γ₂₂(BP LDDR-new partner_i)^*

Note.

These terms were added for positive affect and loneliness, but not for university activities or alcohol use. BP = between-person. WP = within-person. Outcomes are positive affect, loneliness, university activities, and alcohol use. Comparison groups are LDDR for Aim 1 analyses and ongoing LDDR for Aim 2 analyses.
