datecut {PDN}

Generating Optimal cuts for the Data

Description

Performs Cox proportional hazards regression model on patients survival days based on different cutoffs

Usage

datecut(x, surdays, event)

Arguments

x

comorbidity data matrix with column correspond to ICD9 codes and row correspond to each patient

surdays

survival days for each patient

event

indictor variable 1 represent patient died 0 represent patient survive

Details

Building and draw personized disease network

Value

a vector of cutoff points that maximize the Z statistics for cox model between each Diagnosis/Procedure A to another Diagnosis/Procedure B

Examples

comorbidity_data
survival_data
#Select a subset of data for toy example
comorbidity_data = comorbidity_data[c(1:10),]
survival_data = survival_data[c(1:10),]
k1 = datecut(comorbidity_data,survival_data[,1],survival_data[,2])
