I am happy to announce my first Julia package, [ItPropFit.jl](https://github.com/vankesteren/ItPropFit.jl)! It is a package for multidimensional iterative proportional fitting. It has similar features to the R package `mipfp`: the target array can be multidimensional, and the corresponding array margins can themselves be multidimensional as well.

Of course, this is a Julia package so we get a nice speed improvement over mipfp (approximately 5 - 20 times speedup depending on the situation on my computer).

I wrote this package based on [this thread](https://discourse.julialang.org/t/iterative-proportional-fitting-package/60580).

It has full documentation, with an example where I integrate ItPropFit.jl with FreqTables.jl and DataFrames.jl to compute survey weights for a linear regression ([see here](https://vankesteren.github.io/ItPropFit.jl/dev/examples/#Regression-poststratification)).

This is my first Julia package, so I am excited to hear what you think. In case you have comments on the code, I am happy to hear from you! Contributions are also very welcome, of course.

For a rough development to-do list, you can check out the [github issues](https://github.com/vankesteren/ItPropFit.jl/issues).

Congratulations on the package! Consider giving it a more verbose name, that is common practice in Julia. Maybe `IterativeProportionalFitting.jl` or just `ProportionalFitting.jl`?

We try to avoid R’s “soup of letters in package names” to help potential users find your work more easily.

Thanks for the feedback. Will do, for sure. I really like `ProportionalFitting.jl`!
