“…Last, we compute BFR( = 5 × 10 −16 ) exact likelihood estimates of the memory parameter for several observed time series of electric cell-substrate impedance sensing (ECIS) measurements, which is a relatively new tool for monitoring the growth and behavior of cells in culture (Giaever and Keese, 1991). Previous research has suggested that ARFIMA(0, d, 0) models may be appropriate for ECIS measurements, and it has been hypothesized that the memory parameter d may vary by cell type and contamination status (Giaever and Keese, 1991;Tarantola et al, 2010;Gelsinger et al, 2020;Zhang et al, 2020). We consider ECIS measurements from eight experiments, four conducted using Madin-Darby canine kidney (MDCK) cells and African green monkey kidney epithelial (BSC-1) cells.…”
