We have had this question in [OG-USA](https://github.com/PSLmodels/OG-USA) both with regard to the CI computing time restraint and with regard to the PUF. And we have an additional question about storing...

In summary, I think point (3) is the first best. However, I think point (4) has some significant virtues and is my most realistic in the short-term preference. 1. My...

Feels unlucky that this is Issue #666.

I received a question from @tomrod asking to clarify the proposed change in point 4 that allows for different asymptotes as `x --> 0` or as `y --> 0`. The...

@MaxGhenis. The Tibshirani, et al (2011) paper about isotonic regression is really an interpolant that passes through all the points except when the constraint `beta_1

* Aaron Hedlund suggested looking at Mariacristina De Nardi's and Gustavo Ventura's use of parameterized tax functions. * Len Burman suggested higher order polynomials which are extremely flexible. But the...

@tyleransom . I don't think the function has to be everywhere differentiable. It just has to be continuous. The derivatives need not be continuous. For example, back in the day,...

@tomrod Can you expand on this wave in the positive orthant? What is the functional form? How do I constrain it to be monotonically increasing and have the property that...

@MaxGhenis I really like the Tibshirani, et al (2011) paper. I just need to adjust it to the regression version (fitting an average of points) rather than passing through as...

@MaxGhenis I will post some data later today as a testing ground for these functions. I will take this data from the [Tax-Calculator](https://github.com/PSLmodels/Tax-Calculator) output generated in the [get_micro_data.py](https://github.com/PSLmodels/OG-USA/blob/master/ogusa/get_micro_data.py) module of...
