missingdata: Missing data example

Description

Simulated data generated from model $$E(Y_i\mid X) = X, \quad cov(Y_1,Y_2\mid X)=0.5$$

Format

list of data.frames

Details

The list contains four data sets

1. Complete data

2. MCAR

3. MAR

4. MNAR (missing mechanism depends on variable V correlated with Y1,Y2)

Examples

data(missingdata)
e0 <- estimate(lvm(c(y1,y2)~b*x,y1~~y2),missingdata[[1]]) ## No missing
e1 <- estimate(lvm(c(y1,y2)~b*x,y1~~y2),missingdata[[2]]) ## CC (MCAR)
e2 <- estimate(lvm(c(y1,y2)~b*x,y1~~y2),missingdata[[2]],missing=TRUE) ## MCAR
e3 <- estimate(lvm(c(y1,y2)~b*x,y1~~y2),missingdata[[3]]) ## CC (MAR)
e4 <- estimate(lvm(c(y1,y2)~b*x,y1~~y2),missingdata[[3]],missing=TRUE) ## MAR
