MISSINGPLOT: Stata module to draw plot showing patterns of missing values in a dataset

Abstract: missingplot gives a plot showing the incidence of missing values in one or more variables in the current dataset. The horizontal axis shows observation numbers; the vertical axis shows one or more lines, one for each variable shown. Marker symbols show which values are missing. missingplot treats numeric and string variables alike: what is common to both is whether the missing() function returns true. missingplot may be useful for seeing broad patterns in the incidence of missing values, for example blocks of observations with many or all missing values or variables with many or all missing values. It may also be useful for quickly identifying fine structure or notable detail in some instances.
