These are estimated by making statistical assumptions about consumer behaviour.For some goods, customer behaviour can make a dramatic difference to the use-phase emissions.
2) k-nearest neighbour algorithms do not make any statistical assumptions about data, are attractive from an interpretative point of view and are very easy to update with new data.
For the purposes of statistical analysis we therefore divided the OPCRIT+ diagnoses into the following groups for which it was more reasonable to make the statistical assumptions required for accurate calculation of the kappa score.
Some programs make simple statistical assumptions, and these assumptions limit their usefulness.
Our statistical models each make different statistical assumptions, but the main findings of this analysis were robust to the methods used.
Moreover, it is essential to make appropriate statistical assumptions previous to the inventory calculations, because a calculation based on observation-based bootstrapping mean values results in a ∽40% smaller inventory compared to simple mean approach (Table S1).
Second, a systematic comparison is non-trivial since each pipeline makes different statistical assumptions and the hypotheses are not independent.
The strength of the frailty model is that it considers individual baseline injury risks for different players, makes fewer statistical assumptions and also is able to model time-varying covariates.
To globally assess the reliability of these test results while making fewer statistical assumptions, we performed a permutation test (see Methods) to determine if the large number of significant genes we found could easily have arisen by chance.
A key advantage of this non-parametric approach is that it does not make any statistical assumption about the data, thus enabling an arbitrary decision boundary.
