WebBronk Ramsey (2024) has proposed an iterative approach to joint calibration and summarisa-tion. Each determination is rst calibrated individually and a value is drawn from the posterior of ijX ifor i= 1;:::;n. Next, a kernel density estimate is tted to these nspeci c drawn values to generate an initial estimate of the shared age density f( ).
