Transformation of SDE based on change of measure results.


reviously (see the formula ( General change of Brownian motion )) we calculated generic change of measure for Brownian motion $dW_{t}$ . If $a_{t}$ is given by the SDE MATH in the original measure then the change MATH results in MATH where the $d\tilde{W}_{t}$ is a standard Brownian motion with respect to the new probability $E_{a}$ .

According to the formula ( Change of numeraire kernel ), when the change of numeraire is performed, the process $a\left( t\right) $ is given by the expression MATH Thus, MATH for Brownian motion $dW^{M}$ in $M$ -measure. Therefore, MATH or
