1. An audience measurement computing system comprising:
at least one processor; and
memory having stored thereon computer readable instructions that, when executed by the at least one processor, cause the audience measurement computing system to perform operations comprising at least:
identifying, based on first viewing data indicative of viewing of respective television programs by a first set of panelists during a first measurement time period and second viewing data indicative of viewing of the respective television programs by a second set of panelists during a second measurement time period, a first common subset of panelists represented in both the first viewing data and the second viewing data;
identifying, based on third viewing data indicative of viewing of the respective television programs by a third set of panelists during a third measurement time period and fourth viewing data indicative of viewing of the respective television programs by a fourth set of panelists during a fourth measurement time period, a second common subset of panelists represented in both the third viewing data and the fourth viewing data;
in response to a size of the first common subset of panelists satisfying a first threshold, estimating a volume of switching among the television programs from the first measurement time period to the second measurement time period based on a first subset of the first viewing data associated with the first common subset of panelists and a second subset of the second viewing data associated with the first common subset of panelists; and
in response to a size of the second common subset of panelists satisfying a second threshold and not satisfying the first threshold, estimating a volume of switching among the television programs from the third measurement time period to the fourth measurement time period based on a third subset of the third viewing data associated with the second common subset of panelists, a fourth subset of the fourth viewing data associated with the second common subset of panelists, a fifth subset of the third viewing data associated with a first unmatched subset of the third set of panelists that have no panelists in common with the second common subset panelists, and a sixth subset of the fourth viewing data associated with a second unmatched subset of the fourth set of panelists that have no panelists in common with the second common subset of panelists.
