Dear DCM users,
I have a rather technical question about the hemodynamic parameters that are used in the Balloon model of DCM. Even though there are five or six parameters in this model, only three of those (signal decay, transit time and intra-extravascular signal ratio) are estimated.
Does anyone know anything about the decision of not estimating the other parameters? Are their variability not significant enough to make it worth estimating them? (I noticed, that the prior covariance of these parameters are much lower than the ones that are estimated.)
Thank you for your answers and thoughts in advance.
