Webdlm models are a special case of state space models where the errors of the state and observed components are normally distributed. Here, Kalman filter will be used to: filtered values of state vectors. smoothed values of state vectors and finally, forecast provides means and variances of future observations and states. Web4 mei 2024 · One of the best ideas is to name variables after *what they're about* rather than *what type of thing they are*. For example, if you have an array of temperature readings, consider these two names: ```js // not very helpful: let arrayOfNums = [ 98.6, 212 ]; // better! let temperatures = [ 98.6, 212 ]; // even better: are these Fahrenheit or ...
