Title

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

Syntax

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


Description


    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.

    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.
