Comparing log-loss values for a probabilistic suffix tree?

Question

In the PST package one can estimate the prediction quality of individual sequences using the log-loss, e.g:

R> ex2 <- c("a-a-b", "a-b-a-a-b", "b-b-b-b-a") 
R> ex2 <- seqdef(ex2) 
R> predict(S1.p1, ex2, output = "logloss")

logloss
[1] 0.9183 
[2] 0.7311 
[3] 0.9600

How do I compare these log-loss values statistically? Is there a way to show that 0.9183 is significantly different from 0.9600?
