Time Series Causal Impact Analysis in Python | Machine Learning
Рет қаралды 6,137
`CausalImpact` package created by Google estimates the impact of an intervention on a time series. For example, how does a new feature on an application affect the users' time on the app?
In this tutorial, we will talk about how to use the Python package `CausalImpact` to do time series causal inference. You will learn:
👉 How to set the pre and post periods for the causal impact analysis?
👉 How to conduct causal inference on time series data?
👉 How to summarize the causality analysis results and create a report?
👉 What are the differences between the python and the R packages for `CausalImpact`?

Could you elucidate on how to execute a geographical experiment using this? Assuming you have two groups-treatment and control-and for each geographic area, there's associated expenditure and response data, how would you construct the model?

How about just using diff-in-diff? Be very careful with sample ratio mismatch

for predictor x should i choose the variable not impacted after intervention?
@grabngoinfo Жыл бұрын
Yes, the control variables should be highly correlated with the response variable, but not impacted by the intervention.
@programmingwithjackchew903 Жыл бұрын
@@grabngoinfo in this case can I just use person or whatever correlation method to check for correlation and drop the high correlation between the predictor and intervention variable? Do you have any method recommended to check whether the predictor is not impacted after intervention?
