the number of DL coefficients required. `L+1' coefficients for lags 0 to L are returned.

additional arguments (ignored).
Value
A matrix with DL coefficients. Each row corresponds to a specific lag.
Details
The resulting estimates, returned as a matrix, are DL coefficients for the cold and/or the heat effect. Each coefficient
at specific lag represents the log relative risk (of mortality) for one-unit increase in cold (or heat) values.
