naTriplet function

Function to do matched deletion of missing rows from x, y and control variable(s).

The aim in three-way deletions is to retain only the largest number of available data triplets with all non-missing data.

naTriplet(x, y, ctrl)

Arguments

• x: Vector of x data
• y: Vector of y data
• ctrl: Data matrix on the control variable(s) kept beyond causal path determinations

Returns

• newx: A new vector x after removing triplet-wise missing data

• newy: A new vector or matrix y after removing triplet-wise missing data

• newctrl: A new vector or matrix ctrl after removing triplet-wise missing data

Examples

## Not run:

x=sample(1:10);y=sample(1:10);x[2]=NA; y[3]=NA
w=sample(2:11)
naTriplet(x,y,w)
## End(Not run)
