Caliper matching: comparison models within a particular width of your propensity rating from the taken care of units get matched, where the width is usually a portion in the normal deviation from the propensity rating
If units within the procedure and control were well balanced on numerous covariates one after the other, large quantities of observations could well be necessary to overcome the "dimensionality challenge" whereby the introduction of a fresh balancing covariate enhances the minimum amount needed range of observations within the sample geometrically.
A single element of danger evaluation need to entail analyzing whether or not the new Thoughts/ improvements or innovations will prevent the already profitable functions from continuing to operate for the at this time acknowledged level.
