How does the Kalman Filter actually work?

I know that the Kalman filter can be used whenever we have a measurement and transition equation. I also know that the Kalman filter can handle missing data. From my course at university, I know that ...

How does Kalman filtering work backwards?

For time series missing value imputation I am using the Kalman filter/smoothing approach, given in the imputeTS package. As Kalman filter is iterative and needs a view data points to make its estimate ...

Is Kalman filtering a suitable approach to predict data from a set of/or a single feature?

I have multiple repeats of a time series that I would like to use to train a model to predict future repeats. The time series contains feature data (easy to measure) and target data (hard to measure). ...

Kalman filter for time series prediction

I have the information about the behaviour of 400 users across period of 1 months (30 days). Across those 30 days I measure 4 different information (let's call it A,B,C and D), hence I have a total of ...
