Graph propensity score histogram

        psgraph [, bin(#) treated(varname) support(varname) pscore(varname)
                     graph_options]

Description

    psgraph graphs the propensity score histogram by treatment status.

    psgraph can be called without options after psmatch2. In this case
    psgraph will use the generate variables _treated and _pscore. The options
    treated and pscore override this behavior.

Options

    bin(#) specifies the number of intervals to use for accumulating the
        histogram. The default is bin(20).

    treated(varname) specifies treatment indicator variable.  Assumes the
        following: 0 = controls, 1 = treated.

    support(varname) Common support indicator (0/1).

    pscore(varname) specifies the propensity score.
