The influence of individual observations in a correspondence analysis is investigated. Two alternative definitions of 'observation' are possible. For each definition, expressions are presented for influence on the plotting positions of rows and columns of the contingency table being analysed. Formulae for influence on the corresponding eigenvalues (principal inertias) are also given. There are connections for one definition of observation with results for canonical correlation analysis. An example is discussed in detail.
