Multinomial Logistic Regression

In statistics, multinomial logistic regression is a classification method that generalizes logistic regression to multiclass problems, i.e. with more than two possible discrete outcomes. That is, it is a model that is used to predict the probabilities of the different possible outcomes of a categorically distributed dependent variable, given a set of independent variables (which may be real-valued, binary-valued, categorical-valued, etc.).

Multinomial logistic regression is known by a variety of other names, including multiclass LR, multinomial regression, softmax regression, multinomial logit, maximum entropy (MaxEnt) classifier, conditional maximum entropy model.

Is mixed logit model nonparametric model?

I've been reading the articles about mixed logit model, but I wonder whether mixed logit is one of the examples of nonparametric model.

system is computationally singular for mlogit after one hot encoding a variable

I'm building an mlogit model in R. The model works fine but when I add one-hot encoded variables it gives me the "system is computationally singular" which usually comes when correlation is high but my variables are one-hot encoded So Idk how that…

Ordered Logit with Fixed Effects in R

I am trying to implement fixed effects to ordered logit. I know there is a polr function of the MASS package but I have not found the way to implement fixed effects to polr function. I will use country and year as fixed effects. (I have almost 50…

Predicting GLMs

After I split my data frame into a training and test set, I made 2 logit regression tables with the training set. Now I need to use those models to predict the outcome of the test set and use both models to create a table comparing the predicted vs…

Is there a way to get statistics of weights obtained from Tensorflow?

I am interested in developing a logit-based choice model using Tensorflow. I am fairly new to this tool, so I was wondering if there is a way to get the statistics (i.e., the p-value) of the weights obtained from Tensorflow , just like someone would…
