Fast estimation of multinomial (MNL) and mixed logit (MXL) models in R with "Preference" space or "Willingness-to-pay" (WTP) space utility parameterizations in R
This PR includes several additions that will be part of logitr v0.7.0:
[x] A new vignette on benchmarking was added which aims to test the package speed against other similar packages.
[x] A new data set, runtimes, was included, which is exported from this colab notebook used for conducting the benchmark.
[x] Sobol draws are supported via a new drawType argument.
[x] A warning is displayed against using Halton draws after 5 random variables have been specified in a mixed logit model, and users are encouraged to switch to using Sobol draws and increasing the number of draws to at least 200.
[x] Changed the argument name price to scalePar to be more general.
[x] Changed the argument name randPrice to randScale to be more general.
[x] The modelSpace argument is no longer required for specifying a WTP space model as it is redundant. Including a scalePar argument is enough to determine that it is a WTP space model.
