In autoReg: Automatic Linear and Logistic Regression and Survival Analysis

perform automatic regression for a class of coxph

Description

perform automatic regression for a class of coxph

Usage

autoRegCox(
  x,
  threshold = 0.2,
  uni = FALSE,
  multi = TRUE,
  final = FALSE,
  imputed = FALSE,
  keepstats = FALSE,
  ...
)

Arguments

x	An object of class coxph
threshold	numeric
uni	logical whether or not perform univariable regression
multi	logical whether or not perform multivariable regression
final	logical whether or not perform stepwise backward elimination
imputed	logical whether or not perform multiple imputation
keepstats	logical whether or not keep statistic
...	Further arguments to be passed to gaze()

Value

autoRegCox returns an object of class "autoReg" which inherits from the class "data.frame" with at least the following attributes:

attr(*,"yvars)

character. name of dependent variable

attr(*,"model")

name of model. One of "lm","glm" or "coxph"

Examples

require(survival)
require(dplyr)
data(cancer)
fit=coxph(Surv(time,status==2)~log(bili)+age+cluster(edema),data=pbc)
autoReg(fit)
fit=coxph(Surv(time,status)~rx+age+sex+nodes+obstruct+perfor,data=colon)
autoReg(fit)
autoReg(fit,uni=TRUE,threshold=1)
autoReg(fit,uni=TRUE,final=TRUE) %>% myft()
data(colon_s,package="finalfit")
fit=coxph(Surv(time,status)~age.factor+sex.factor+obstruct.factor+perfor.factor,data=colon_s)
autoReg(fit,uni=TRUE,threshold=1)
autoReg(fit,uni=TRUE,imputed=TRUE)
