Note the ties between the lengthscales of ``Kanova`` to keep the number of lengthscales equal to 2. On the other hand, there are four variance terms in the new parameterization: one for each term of the right hand sign of the equation above. We can illustrate the use of this kernel on a toy example:: Note the ties between the lengthscales of ``Kanova`` to keep the number of lengthscales equal to 2.
