., 3 contending with cold and still days (cold = high demand; still = wind is low, which implies a dependency between the two); measuring variables together through more advanced statistical methods; re-scaling historic data to use in statistical models to assess risk for future years; dealing with the uncertainty that re- scaling introduces (e.g. building in the impact of climate change, behaviour change); crucial need to reflect lack of knowledge in any decisions made (e.g. on capacity payments) by accounting for uncertainty and propagating this through into final results; many issues in security of supply analyses are common across multiple different applications, such as forensic science (when accounting for uncertainty in decision-making).
