setcert($self,certaintyvar)

This transform sets the certainty characteristic of an input variable (of any type) to the values contained in the column certaintyvar. This transform is useful for modifying the certainty values generated by time merge. The output variable must be the same as the input variable. The certainty characteristic, the value of certaintyvar, is inclusively between 0 and 1, and has granularity. That is, it can only be set to a group of predetermined values; the values that you set are automatically rounded to the nearest valid certainty.
