 utput equations for linear compartmental models with prescribed orders\nAb
 stract: Linear compartmental models are linear systems of ODEs that are de
 termined by a graphical structure G. A common question that arises when pe
 rforming parameter estimation is whether the parameters in our model can b
 e recovered uniquely from perfect input-output data (i.e. data from variab
 les we can measure). One way to assess this is by studying the coefficient
 s of input-output equations, which are obtained via differential eliminati
 on. In this talk, we discuss a linear algebra-based algorithm that allows 
 us to compute "nice" sets of input-output equations that have prescribed o
 rders for the derivatives that appear in the equations.\n
