 where <math display="inline">\partial f/\partial x</math>  is the Jacobian matrix. While <math display="inline">\overset{\mbox{ˆ}}{P}</math>  can be estimated from the estimation of <math display="inline">x</math> , the Jacobian can be derived from ''f'' , in this case by differentiating the expressions  [[#eq0055|(11)]]  ;  [[#eq0060|(12)]] . It is possible to estimate the variances of  [[#eq0055|(11)]]  ;  [[#eq0060|(12)]]  without linearization, see e.g., [[#bib18|Tellinghuisen (2001)]] . The advantage of using [[#eq0090|(18)]]  is that it yields the covariance between the estimates directly.
