Similarly, the exact time to death is not known as the data set contains only the death reporting date which is usually after the actual death date. Therefore, the actual death date lies between the last clinic visit of the patient and the death reporting date. Although interval-censored ...
Fine-scale data on animal position are increasingly enabling us to understand the details of animal movement ecology and dead-reckoning, a technique integrating motion sensor-derived information on heading and speed, can be used to reconstruct fine-scale

Therefore, the learner cannot simply combine all of the source data together to train a predictor. A possible solution to this problem is the Mixture of Experts (MOE) approach. MOE is an ensemble learning technique that involves training multiple experts on different sub-tasks of a predictive ...
The resulting model contains four predictors plus an intercept and captures more than 99% of the variance of the norm data. For a more detailed summary, cNORM’s ‘summaryModel’ can be applied to the norm model: # Compute best regression model, default R2 = 0.99 model <- bestModel(...
However, with enough data and an identifiable, Gaussian state-space model, the filtered and smoothed states, and a likelihood based on them, can be computed using the diffuse Kalman filter. Represent a static, initial state as unknown parameter by attributing to it an infinite variance....
