Gene regulat.ry.net.orks （GRNs） cont.ol t.e product.on of prot.ins in cells. It.is well-known t.at.t.is process is not.det.rminist.c. Numerous st.dies employ.d a non- det.rminist.c t.ansit.on st.uct.re t. model t.ese net.orks. However, it.is not.realist.c t. expect.st.t.-t.-st.t. t.ansit.on probabilit.es t. remain const.nt.t.roughout.an organ- ism＇s lifet.me. In t.is work, we focus on modeling GRN st.t. t.ansit.on （edge） variabilit. using an ever-changing set.of propensit.es. We suspect.t.at.t.e source of t.is variat.on is due t. int.rnal noise at.t.e molecular level and can be modeled by.int.oducing addi- t.onal st.chast.cit. int. GRN models. We employ.a bet. dist.ibut.on, whose paramet.rs are est.mat.d t. capt.re t.e pat.ern inherent.in edge behavior wit. minimum error. Addit.onally. we develop a met.od for obt.ining propensit.es from a pre-det.rmined net.ork.
