2 + GP

yes

Year-wise model and GP with year as fixed effect

 

with kinship

   

and GY modeled using kinship

A2

2-stg-Kin

TS1, TS2, TS3

2

yes

Across years model with GP included in the 2nd

     

stage and GY modeled using kinship

A3

2-stg-Kin-het

TS1, TS2, TS3

2

yes

Across years model with GP included in the 2nd

     

stage and GY modeled using kinship. Allows heterogeneous

     

rogeneous variance among years in the GY interaction effect

A4

3-stg-NoKin

TS1, TS2, TS3

3

no

Across years model for the TS using no kinship to model GY.

     

Third stage is GP

A5

3-stg-Kin

TS1, TS2, TS3

3

yes

Across years model for the TS. Uses kinship in the 2nd stage

     

of the TS to model GY. Third stage is GP
