Equivalent weights. Unnecessary confusion

[Unnecessary operations in shoulder surgery: "table of confusion" applied to "field of confusion"].

Attributing a surgical procedure as unnecessary or necessary is a binomial classifier that can be analysed in a so called "table of confusion". Ambroise Parré (1510 - 1590) observed that wound treatment with hot oil was harming instead of healing, and concluded that it should be discarded as "standard of care". Still today, the answer to the same question "What is the standard of care?" is deci...

Errors in Dispensing Due to Confusion of Weights

Simplified equivalent multiple baseline solutions with elevation-dependent weights

Since the assumption of all stations tracking the same satellites with identical weights was previously employed by Shen and Xu (GPS Solut 12:99–108, 2008) to derive the simplified GNSS singleand double-differenced equivalent equations, this supplementary paper expands these simplified equations in the case of each station tracking different satellites with elevation-dependent weights. Numerica...

The equivalent-weights particle filter in a high-dimensional system

In general, particle filters need large numbers of model runs in order to avoid filter degeneracy in high-dimensional systems. The recently proposed, fully nonlinear equivalentweights particle filter overcomes this requirement by replacing the standard model transition density with two different proposal transition densities. The first proposal density is used to relax all particles towards the...

An exploration of the equivalent weights particle filter

Particle filters are fully non-linear data assimilation techniques that aim to represent the probability distribution of the model state given the observations (the posterior) by a number of particles. In high-dimensional geophysical applications the number of particles required by the sequential importance resampling (SIR) particle filter in order to capture the high probability region of the ...
