Hi, We have created a cox regression model (coxph) and exported from R as PMML using the Rattle package. The resulting PMML is a standard Regression model in the format y=b1*x1+b2*x2+??.bn*xn: risk= (0.027968680616809*dropped_Calls)+(0.00777220409115466*helpdesk_Calls) The PMML is included at the end of this post. Cox Regression is usually in this format: h(t)= h0(t)*e^(b1*x1+b2*x2+??.bn*xn)

Dear All, I want to save the XML representation of a model using PMML. Then I want to read the model and predict using the model and a new dataset. This is described in this blog post : https://www.r-bloggers.com/predictive-modeling-using-r-and-the-openscoring-engine-a-pmml-approach/ I am able to save the PMML representation of the model. I am not able to read this representation convert it
