Analysis of relative abundances with zeros on environmental gradients: a multinomial regression model. [PDF]
Ecologists often analyze relative abundances, which are an example of compositional data. However, they have made surprisingly little use of recent advances in the field of compositional data analysis.

Nuclear penalized multinomial regression with an application to predicting at bat outcomes in baseball. [PDF]
We propose the nuclear norm penalty as an alternative to the ridge penalty for regularized multinomial regression. This convex relaxation of reduced-rank multinomial regression has the advantage of leveraging underlying structure among the response ...

Multiclass Classification by Sparse Multinomial Logistic Regression [PDF]
In this paper we consider high-dimensional multiclass classification by sparse multinomial logistic regression. We propose first a feature selection procedure based on penalized maximum likelihood with a complexity penalty on the model size and derive the nonasymptotic bounds for misclassification excess risk of the resulting classifier.

Comparing methods for risk prediction of multicategory outcomes: dichotomized logistic regression vs. multinomial logit regression [PDF]
Background Medical outcomes of interest to clinicians may have multiple categories. Researchers face several options for risk prediction of such outcomes, including dichotomized logistic regression and multinomial logit regression modeling.

Approximate Sparse Multinomial Logistic Regression for Classification
We propose a new learning rule for sparse multinomial logistic regression (SMLR). The new rule is the generalization of the one proposed in the pioneering work by Krishnapuram et al. In our proposed method, the parameters of SMLR are iteratively estimated from log-posterior by using some approximations.

Analysis of genomic signatures in prokaryotes using multinomial regression and hierarchical clustering [PDF]
Background Recently there has been an explosion in the availability of bacterial genomic sequences, making possible now an analysis of genomic signatures across more than 800 hundred different bacterial chromosomes, from a wide variety of environments ...
