Exponential Weighting #11

Open MikeJohnPage opened 2 years ago

MikeJohnPage commented 2 years ago

Currently when calculating composite scores in calculate_composite_score(), normalised ranks are not exponentially transformed before summing. This means extremes of the distribution won't be emphasised. Add step into function and recompute scores.

Experimental risk_index branch currently implements a fix: https://github.com/britishredcrosssociety/resilience-index/blob/risk_index/indices/disasters-emergencies/england/ltla/build-index.R#L78
