R code and data for: "Reducing and meta-analysing estimates from distributed lag non-linear models"

An illustration on methods for reducing estimates of bi-dimensional exposure-lag-response associations obtained by DLNMs from multiple studies, and then pooling them. The example reproduces the example included in the paper: Gasparrini A, Armstrong B. Reducing and meta-analysing estimates from distributed lag non-linear models. BMC Medical Research Methodology. 2013;13(1):1. The code set contains the following: [1] regEngWales.csv stores the daily time series data from 10 locations corresponding to regions of England and Wales in the period 1993–2006; [2] the numbered files from 01.prep.R to 06.metareg.R reproduce the results of the illustrative example. The code uses functions in the R packages dlnm and mvmeta.
