However, the set-up of the present text is completely different. The models that you have seen thus far are deterministic models. 0000106789 00000 n %%EOF From a pragmatic point of view, both will construct the same model - its just that each will take a different view as to origin of the stochastic behaviour. 5 Howick Place | London | SW1P 1WG. A deterministic model is specified by a set of equations that describe exactly how the system will evolve over time. This is mainly due to solid mathematical foundations and theoretical richness of the theory of probability and stochastic processes, and to sound 0000041781 00000 n xref 0000024330 00000 n 0000014138 00000 n 0000059995 00000 n Although many ways have been proposed to model uncertain quantities, stochastic models have proved their flexibility and usefulness in diverse areas of science. 2. x�b``�e``�``f`P,f`@ �+���@n�Ң��{~ָX@a7��R�=6I&r�*[,@�D>~����r�r� SD ����1���i�o�������[���q���f��8�0�l � ��,u endstream endobj 135 0 obj<> endobj 136 0 obj<> endobj 138 0 obj<>/XObject<>/ProcSet[/PDF/Text/ImageB]/ExtGState<>>>>> endobj 139 0 obj<>stream �~7�$�����DP0�U��������b��c��nz���e���3aި��~p%�D�J��Ȍ��&[��{�-��%>�8fA2.¸�3���K��w���)�q���1vI�p�X�/�[����J:�&H''�)iS?Ʃ!�a�x�+����n��e��Ȳn��.Dwx�lP3̥F���/I�!�9��ʗ�X�o ���y endstream endobj 140 0 obj<> endobj 141 0 obj<> endobj 142 0 obj<> endobj 143 0 obj<> endobj 144 0 obj<> endobj 145 0 obj<>/Width 1728/Height 151/BitsPerComponent 1/ColorSpace/DeviceGray/Decode[1 0]/Type/XObject/Name/im1/Subtype/Image>>stream ������?�%+���� �I���r ��}�����A*�VHr��G� Stochastic models based on the well-known SIS and SIR epidemic models are formulated. &�e �������@� Y����w����}��>������������������������� � endstream endobj 149 0 obj<>/Width 1728/Height 151/BitsPerComponent 1/ColorSpace/DeviceGray/Decode[1 0]/Type/XObject/Name/im2/Subtype/Image>>stream Article. 0000001011 00000 n The random nature of gene expression is well established experimentally. 0000001070 00000 n Mathematical modeling provides a means of understanding the factors leading to the observed stochasticity. At the same time, the most likely value for volatility converges to zero. In this model, instantaneous volatility is a martingale but the variance of volatility grows unbounded.
