glmpathcr: An R Package for Ordinal Response Prediction in High-dimensional Data Settings
نویسنده
چکیده
This paper describes an R package, glmpathcr, that provides a function for fitting a penalized continuation ratio model when interest lies in predicting an ordinal response. The function, glmpath.cr uses the coordinate descent fitting algorithm as implemented in glmpath and described by (Park and Hastie 2007a). Methods for extracting all estimated coefficients, extracting non-zero coefficient estimates, obtaining the predicted class, and obtaining the class-specific fitted probabilities have been implemented. Additionally, generic methods from glmpath including summary, print, and plot can be applied to a glmpath.cr object.

Comparison of Ordinal Response Modeling Methods like Decision Trees, Ordinal Forest and L1 Penalized Continuation Ratio Regression in High Dimensional Data
Background: Response variables in most medical and health-related research have an ordinal nature. Conventional modeling methods assume predictor variables to be independent, and consider a large number of samples (n) compared to the number of covariates (p). Therefore, it is not possible to use conventional models for high dimensional genetic data in which p > n. The present study compared th...

متن کاملordinalgmifs: An R Package for Ordinal Regression in High-dimensional Data Settings
High-throughput genomic assays are performed using tissue samples with the goal of classifying the samples as normal < pre-malignant < malignant or by stage of cancer using a small set of molecular features. In such cases, molecular features monotonically associated with the ordinal response may be important to disease development; that is, an increase in the phenotypic level (stage of cancer) ...
متن کاملModeling Paired Ordinal Response Data
About 25 years ago, McCullagh proposed a method for modeling univariate ordinal responses. After publishing this paper, other statisticians gradually extended his method, such that we are now able to use more complicated but efficient methods to analyze correlated multivariate ordinal data, and model the relationship between these responses and host of covariates. In this paper, we aim to...
متن کاملStatistical Methods to Enhance Clinical Prediction with High-Dimensional Data and Ordinal Response
Advancing technology has enabled us to study the molecular configuration of single cells or whole tissue samples. Molecular biology produces vast amounts of high-dimensional omics data at continually decreasing costs, so that molecular screens are increasingly often used in clinical applications. Personalized diagnosis or prediction of clinical treatment outcome based on high-throughput omics d...
