Functions we need to construct indices
make_idx( data, vars, sgn = 1, scale = FALSE, seed = 12345, diplaymessage = "FALSE" )
| data | Given dataset containing variables |
|---|---|
| vars | variable used construct a composite index from the first principal component after multiple imputation. |
| sgn | Direction - Set sgn=-1 to reverse the direction of the index. |
| scale | Scale - Set scale=TRUE to use scaling during the PCA calculation |
| seed | for reproducibility |
| diplaymessage | diplay message TRUE OR FALSE |
if (FALSE) { }
