Heat map of cross-correlation coefficients for the Austrian data.
Suizid, Selbstmord = ‘suicide’ in English; Depressionen = ‘depression’ (plural in German). Numbers in column headers refer to lags in months. Idealized patterns reflect what could be expected if search volumes predicted suicide rates. In the observed patterns, frames highlight statistically significant (p < .05) coefficients.
