Daniel is right: -table- may temporarily drop observations after a -preserve-. Goodness knows how many commands do that silently on your behalf! But "drop" is still the wrong word because it can be misread as -drop-. The point of view that the observations are not being shown is the more important one. Precision is important. Some users write of modelling commands dropping collinear variables, when they mean "omitting", or of having missing values when it turns out that they mean gaps in their data. Usually the wording can be decoded, but ambiguities can also be reduced by using the -cmdname- notation and sticking as closely as possible to Stata's own terminology.
