Abstract: nearmrg performs nearest match merging of two datasets. nearmrg matches observations that are closest on the variable specified in nearvar(). Options upper, lower, and roundup allow some adjustments to how closest is defined. Additional variables may be specified in an optional varlist and these variables are treated as standard merge variable which must match exactly. This option allows nearest matching within subsets defined by the varlist. nearmrg was designed as a way to use lookup tables that have binned or rounded values on the variable of interest.
