- a Set-up for \(G\ge 2\) stratum each defined on the same Lexis diagram with \(A\) age groups and \(P\) calendar periods
- b Model \(df\) for N-PH is \(2G\left(A+P-2\right)\)
- c Intercept terms for log-scale estimable functions are: \(\mu_{FTT}^{(k)}=\log CrossAge^{(k)}\left(a_\ast\right)\), \({\mu }_{CAC}^{(k)}=\mathrm{log}{FTT}^{(k)}\left({p}_{*}\left({p}_{ref}\right)\right)\), \(\mu_{LAC}^{(k)}=\log{FCP}^{(k)}\left(c_\ast\left(c_{ref}\right)\right)\), \(\mu_{FCP}^{(k)}=\log{LongAge}^{(k)}\left(a_\ast\left(a_{ref}\right)\right)\)
