ISR {ISR}

Iterated score regression

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

is the estimator on the ISR method

MSEISR

is the MSE value of the ISR method

MAEISR

is the MAE value of the ISR method

REISR

is the RE value of the ISR method

GCVISR

is the GCV value of the ISR method

timeISR

is the time cost of the ISR method

Examples

 library(MASS)   
 n=100;p=10;per=0.1
 X0=data=matrix(mvrnorm(n*p,0,1),n,p)
 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)
