ISR: Caculate the estimator on the ISR method

In ggbggbggb/ISR: The Iterated Score Regression-Based Estimation Algorithm

Description

Caculate the estimator on the ISR method

Usage

ISR(data = 0, data0, real = TRUE, example = FALSE)

Arguments

data	is the orignal data set
data0	is the missing data set
real	is to judge whether the data set is a real missing data set
example	is to judge whether the data set is a simulation example.

Value

XISR, MSEISR, MAEISR, REISR, GCVISR,timeISR

Examples

 library(MASS)   
 etatol=0.9
 n=100;p=10;per=0.1
 mu=as.matrix(runif(p,0,10))
 sigma=as.matrix(runif(p,0,1))
 ro=as.matrix(c(runif(p,-1,1)))
 RO=ro%*%t(ro);diag(RO)=1
 Sigma=sigma%*%t(sigma)*RO
 X0=data=mvrnorm(n,mu,Sigma)
 m=round(per*n*p,digits=0)
 mr=sample(1:(n*p),m,replace=FALSE)
 X0[mr]=NA;data0=X0
 ISR(data=data,data0=data0,real=FALSE,example=FALSE)
