I am using `pygam.gam( )` that is fitting all the features with splines (without my imposing any specific `term` to any feature), so is it fair to say that GAM is equivalent to multivariate adaptive r…

Hi, thank you for sharing such wonderful work!
I want to generate 7-dof joint trajectory using non-zero start and end velocity. I have checked out the previous issues about this problem, but I can't …

I need to differentiate through the `DataInterpolations.jl` wrt to the new evaluation points and the input data.
Here a MWE
```
n = 64
x = vcat([0.], sort(rand(n-2)), [1.])
x1 = vcat([0.], sort(r…

I have found that I can create a spline on training data and then apply to test data like this:
#create
x1= dmatrix("cr(x, df=3) - 1", {"x":TRAIN_DATA.VARIABLE.values})
#apply

I am trying to build splines with discontinuities by increasing the multiplicity of the knot at the discontinuity. My understanding is that this can be achieved through splinter's support for custom k…

hi @adolgert!
How hard would it be to introduce penalty matrices (penalizing, for example second derivatives) to these splines? Basically, if $X$ is the model matrix of the spline, $y$ the data, $\…

Most of the base R packages return `TRUE` for `available_on_cran()`. Feels like all of these should return `FALSE`.
``` r

For unclear reasons, `scipy.signal.spline_filter` casts complex inputs to single precision.
Also the `hcol` array used is single-precision, which may cause inaccuracy.
### Reproducing code example…
