However, when random slopes were added to the models, performance of the Poisson mixed model increased considerably and performed more or less the same as the two-part joint mixed model (binomial/Poisson).
This can help mitigate the lack of track record on circular models' performance, as investors can proxy performance data by looking at similar models.
Since the models' performance is so similar, and they mimic the polls so closely, one answer, especially in the immediate run-up to elections, is that we should regard them as an appendage, or addition, to the latest crop of poll numbers, rather than as an independent source of information.
Table 9 Models performance comparison, "Cod".
The models performance was stable in larger data sized problems.
The models performance had a mean crossvalidation r2 of 0.13.
Ten statistical indicators were used to assess models performance.
Figure 5 Models' performance for large flows and under different training set relative sizes.
The genetic algorithm did not improve the models performance significantly compared with the nonlinear mathematical optimization.
Furthermore, we examine the impact of some exogenous variables ((X_t), (Y_t)) on the forecast models performance.
Using the calibrated models, performance of the system was analyzed for different climatic zones of India.
