Is it possible to do this with SPSS? Is there a way to save the model predicted outcome while doing Cox regression? I saw that when I do multinomial logistic regression in SPSS, I can save the predicted category and compare it with the actual category. I don't have that option in Cox. Is it possible to make ROC curves for different Cox models. Uses and limitations of Cox, ROC & other statistics AAIM 2012 Mike Fulks Cox regression analysis • The most common analysis seen in medical journals • Uses a regression algorithm to determine how well a finding “A” explains results “B” • It allows use of data the way it. Armitage used logistic regression but I wonder if it's possible to use a model from the survival package, the survivalROC gives a hint of this being possible but I can't figure out how to get that to work with a regular Cox regression. I would be grateful if someone would show me how to do a ROC. In cox regression analysis in SPSS,. I performed Cox regression analysis to look for predictors of the outcome which included various explanatory variables such. I ran a ROC curve on SPSS. 09/01/2017 · I don't know what you mean by that. The Cox regression model does not predict any dichotomous outcome. It is a model of time to events. The Harrell C statistic which is also the area under an ROC curve for a Cox regression model relates to the accuracy of its predictions about whose "death" precedes whose.

We have run two different models and have areas under the ROC curve of.5785 and.8330. Next, we will use the two linear predictors with the roccomp command to get a test of the differences in area under the ROC curve. How do I create ROC curve for combined biomarkers in SPSS?. if I did the "probabilities" by binary logistic regression, in the roc curve it asks if the smallest. I ran a ROC curve on SPSS.

Logistic regression is useful for situations in which you want to be able to predict the presence or absence of a characteristic or outcome based on values of a set of predictor variables.

A Review on ROC Curves in the Presence of Covariates 23 1. INTRODUCTION ROC curves are a very useful instrument to measure how well a variable or a diagnostic test is able to distinguish two populations from each other. In a previous post we looked at the popular Hosmer-Lemeshow test for logistic regression, which can be viewed as assessing whether the model is well calibrated. In this post we'll look at one approach to assessing the discrimination of a fitted logistic model, via the receiver operating characteristic ROC curve.
