From: A signal detection method for temporal variation of adverse effect with vaccine adverse event reporting system data

 

j-th Vaccine- AE

Other combinations

 

i-th Year

\( {n}_{ij} \)

\( {n}_{i.} \). - \( {n}_{ij} \)

\( {n}_{i.} \).

Other years

\( {n}_{. j}-{n}_{ij} \)

\( \Big({n}_{..}-{n}_{i.\Big)}-\left({n}_{. j}-{n}_{i j}\right) \)

\( {n}_{..}-{n}_{i.} \)

 

\( {n}_{. j} \)

\( {n}_{..}-{n}_{. j} \)

\( {n}_{..} \)
