Description: Data on perfomance, relationship quality, motivation, and
cohesion among 33 sports dyads (badminton, figure skating, synchronised
swimming). Various multi-level models fit (i=dyad, j=individual w/in dyad):

Null model:
Level 1:   Y_ij = B_0i + e_ij
Level 2:   B_0i = G_00 + u_0i

IAO Model:
Level 1:   Y_ij = B_0i + B_1i(Indiv Motivation_ij) + e_ij
Level 2:   B_0i = G_00 + G_01(Dyad Cohesion_i) + G_02(Dyad Motivation_i) +u_0i
           B_1i = G_10

SAO Model:
Level 1:   Y_ij = B_0i + B_1i(Indiv Motivation_ij) + e_ij
Level 2:   B_0i = G_00 + G_01(Dyad Cohesion_i) + G_02(Dyad Motivation_i) + u_0i
           B_1i = G_10 + G_11(Dyad Cohesion_i) + G_12(Dyad Motivation_i) + u_1i
