paverage --- Generates series of averages in a panel dataset.


paverage varlist, p(#) indiv(varname) yr(varname)


paverage (pronounced p-average) generates series of averages in a panel dataset. In the process, the labels of the original variables, if present, are attached to the average variables. The time period must be a multiple of the subperiod over which averages need to be calculated. Using series of averages is a common way of reducing business-cycle effects and measurement error when analyzing a panel dataset with a long time period.

A side-effect of taking variable averages is that some variations in the data will be lost.

Note that paverage works on any yearly compiled balanced panel datasets.


+---------+ ----+ Options +----------------------------------------------------------

p(#) indicates the number of years over which averages need to be calculated. # ranges from 2 to 10. For example, specifying p(5) will create a 5-year average dataset.

indiv(varname) indicates the identifier variable which may hold country, individual, or firm names or identification numbers.

yr(varname) specifies the variable containing the years.
