Except below from [Xu et al. (2018)](https://cdnsciencepub.com/doi/10.1139/cjfas-2017-0446) describes a tuning algorithm for the hyper-parameter sigma_s used with semi-parametric selectivity (which ha…

(Just a vague idea about how this can be incorporated in a generic way.)
Kerby uses parameter classes in several model, mainly to handle various transformations.
mlefit uses parameter classes includi…

An idea for a new wrapper model when we have weights available in the estimation.
Use IRLS as in RLM on top of current MLE models.
e.g. a simple implementation would use an existing model and model c…

When solving a system of linear equations, using the MKL or OpenBLAS native providers, I have often found that the results are not accurate.
For a square matrix the system can be solved calling eithe…

Hi, thanks again for open sourcing your repository. Could you provide a simple example on how to apply your model for discovery of ODE systems (e.g. 2 variables). I had a look at the [lorenz.py](https…

Just parking a vague idea
In several cases we want to estimate additional statistics to help in the interpretation, these are like parameters that don't show up in the null model

example `if type(corr1) == np.ndarray:`
should either use `is` or `isinstance`.
Most likely we want `is` in those cases, i.e. rule out subclasses of ndarray (which might not have compatible behavior…
