Table 6.

TRF has a pyro ring at its N-terminal.

T = TRF peptide consists of glu-his-pro blocked at the N-terminal by a pyro ring
~T = TRF consists of glu-his-pro blocked by an acetyl group at the N-terminal
E1 = glu-his-pro was known to form an internal ring at the N-terminal during acetylation
E2 = synthetic pyro-glu-his-pro was active in the assay while the acetyl form was not
E3 = the pyro and acetyl forms are not as active as the purified TRF in the assay
Probability	Value	Code	Description
P(T)=	0.61		Posterior of acetyl-glu-his-pro
P(~T)=	0.39		1—prior
P(E1|T)=	0.6	WC	A pyro ring at the N-terminal is weakly consistent with the acetylation of glu-his-pro
P(E1|~T)=	0.4	WI	Acetyl-glu-his-pro is weakly inconsistent with acetylation forming a pyro ring
P(E2|T)=	0.7	SC	TRF as pyro-glu-his-pro is strongly consistent with its TRF activity
P(E2|~T)=	0.3	SI	TRF as acetyl-glu-his-pro is strongly inconsistent with its absence of TRF activity
P(E3|T)=	0.4	WI	TRF as pyro-glu-his-pro is weakly inconsistent with its lower TRF activity than natural TRF
P(E3|~T)=	0.4	WI	TRF as acetyl-glu-his-pro is weakly inconsistent with its lower TRF activity than natural TRF
P(T|E1-E3)=	0.84	Confirm

In the body of the table prior and posterior probabilities are shaded in yellow. Conditional probabilities are shaded green for the theory being tested and pink for the alternative. Bolded words in the Description column indicate the relationship between the theory and evidence in accord with the abbreviations in the Code column.
