*3.4. Linssen's MoN*

In order the correct the deficiency in Beale's MoN, Linssen proposed a modification to obtain the following MoN [20]

$$\mathcal{M}^\* = \sqrt{\rho^2 \frac{\sum\_{i=1}^m ||\mathbf{h}(\mathbf{x}\_i) - \mathbf{T}(\mathbf{x}\_i)||^2}{\sum\_{i=1}^m ||\mathbf{h}(\hat{\mathbf{x}}) - \mathbf{T}(\mathbf{x}\_i)||^4}}. \tag{49}$$
