Hi all,


I am a phylogenetic student, I'm running SH test to examine free (tree1) and constrained (tree2) trees using R phangorn package. The outputs are like the following and i'm confused how should i interpret them!!!
 
Trees      ln L           Diff ln L    p-value
[1,]     1 -1422.921   0.00000  0.4952
[2,]     2 -1457.282  34.36085  0.0201

Why it gives us two p values? Would you please help me with that?

Regards,
Vahab
