Analyzing temperature effects on mortality within the R environment: the constrained segmented distributed lag parameterization

Here we present and discuss the r package modtempeff including a set of functions aimed at modelling temperature effects on mortality with time series data. the functions fit a particular log linear model which allows to capture the two main features of mortality-temperature relationships: nonlinearity and distributed lag effect. penalized splines and segmented regression constitute the core of the modelling framework. we briey review the model and illustrate the functions throughout a simulated dataset.
