We have telco business case, we installed picocells in some areas and have collected daily upload, download as well as picocell upload, download data for last 3 months. I have earlier 3 years daily upload, download numbers as well when there was no picocells installed.
Goal is to statistically prove causation that increase in data usage, if any is due to picocell and not due to something else. If proven, it could help reduce churn.
What should be the solution approach? Any ideas?
