Nettet27. mar. 2024 · Introduction to Dynamic Linear Models for Time Series Analysis Marko Laine Dynamic linear models (DLM) offer a very generic framework to analyse time series data. Many classical time series models can be formulated as DLMs, including ARMA models and standard multiple linear regression models. Nettet5. aug. 2024 · I think Linear regression is more feasible than time series analysis here, becasuse I think you have lots of categorical variables, and time series analysis works better with purely numeric data. Many of your categorical vriables are likely to be NA, and many might have high cardinality and thus might not be suited for one-hot-encoding.
