The more levels you have in your ordinal variable, the more option 1 would be preferred over option 2 - at some point you have more dummy variables than you want to deal with and interpret. I don't think there is a way to "force" an independent variable to be ordinal.
Another approach is given by Rennie and Srebro, who, realizing that "even just evaluating the likelihood of a predictor is not straight-forward" in the ordered logit and ordered probit models, propose fitting ordinal regression models by adapting common loss functions from classification (such as the hinge loss and log loss) to the ordinal case ...
This estimates the probability of ranked outcomes based on the predictor values. Ordinal regression suits analysis of ordinal scales with more than two categories, as binary logistic regression is better for dichotomous outcomes. Visualizations. Visualizing ordinal data maintains the order and ranking of categories.
Sep 9, 2020 · In the same population, proportional rank was also a better predictor of females' faecal glucocorticoid concentrations than simple ordinal rank . These studies highlight the need to understand the contexts in which one rank metric predicts a trait better than another.

Jan 11, 2021 · Some basic ordinal models assume that an unobserved latent variable underlies the ordinal response variable. The observed variable is considered as a categorization of the underlying continuous response. The approach yields simple models but makes assumptions that are not really needed for the construction of ordinal models.

May 5, 2015 · In this sense, ranking is an easier problem than ordinal regression: from the numerical labels you can construct an order, but not necessarily the other way round. This is better explained with an example. Suppose that we have the following pairs of (sample, label): $\{(x_1, 1), (x_2, 2), (x_3, 2)\}$.

Oct 1, 2024 · Participants respond to an ordinal variable with k = 5. The simulation is performed using a for loop that repeats 1000 times the data simulation, model fitting, and extracts the p-value for the β 1. The power is then estimated as the number of p-values lower than the critical level over the number of simulations.
