Estimation of a Poisson log linear regression to model the temperature effect on health using the ‘constrained segmented distributed lag parameterization’ which allows to account simultaneously for typical features of temperature effects: nonlinear effect delayed over several days.

Package modTempEff fits a Poisson log linear regression to model the temperature effect on health using the ‘constrained segmented distributed lag parameterization’ which allows to account simultaneously for typical features of temperature effects: nonlinear effect delayed over several days. Fitting is performed by the function tempeff and 'print', 'summary', 'plot', 'anova' and 'coef' methods are included to summarize and to display results.
