Meta-Learning: Boosting and Bagging for Time Series Forecasting

صورة
I am always struggled to model the changes in gasoline prices as a categorical variable, especially in a small amount of time-series data. The answer to improving the performance of modeling such a dataset can be to combine more than one model. This method of combining and aggregating the predictions ...

Regime Switching State Space Model with R code

صورة
This post explains a Markov regime switching state space model. The bottom line is two-fold: 1) expanding states by each regime transitions and 2) collapsing each updated estimates for the next state prediction. The step 2) is necessary to fix t...
