Using user defined functions with fittable parameters in MARS

8

Hi I was wondering if the following feature was included or could be included in MARS. to explain the above let me give an example. If I am simulating gas...

Alternatives to step-wise regularization

10

After our discussion in #157. I decided to read up more on the advantages/disadvantages of using other regularization techniques. I found [CMARS 2012](https://www.researchgate.net/publication/233429692_CMARS_A_new_contribution_to_nonparametric_regression_with_multivariate_adaptive_regression_splines_supported_by_continuous_optimization) [CMARS 2008](https://www.researchgate.net/publication/225614871_A_new_approach_to_multivariate_adaptive_regression_spline_by_using_Tikhonov_regularization_and_continuous_optimization) ,where the authors use Ridge...

Does the algorithm use multiple threads in fitting

2

Hi I've come to a point where i want to fit multiple MARS models independently at the same time. However I am finding that when I try to fit multiple...

Support missing data in response matrix, y

5

A recent change allows missing data in the design matrix. Might the same be done for the response matrix? I am adapting EARTH to the time series case, per TSMARS...

Fit Limits

5

Hi I wondered if it would be possible to add limits to the fitting algorithm, e.g y >0 at x= -inf. I would hope that this functionality is within the...

init parameter check_every not work

3

Hi: I am trying to use the parameter check_every to control my fitting time, but I found it didn't make any differences when I change the init parameter check_every. So...
