Some past history on dssg web,
Initially dssg web started off as a wordpress blog.
Someone was originally assigned to developed it in Ruby but it never materialized.
To make things simple, I simply changed it to a static blog since the web server ($5 digital ocean) sponsored by Kaixin was also hosting 5 other web server.
We did discussed before on doing a learning platform https://open.edx.org/ or a forum https://www.discourse.org/ but so far none materialized due to cost ( SSL and Servers)
Any prototype or discussion is greatly welcomed!
Folks, have been analyzing customer lifetime value of a firm. Not sure, if I am in the right direct. Appreciate any help.
The problem is as follows:
A customer cohort that started during a particular period, have data on sessions and purchases. Sessions indicate the lifetime and purchases the value derived. Have derived the survival function from Kaplan-Meier curve, and integrated as follows:
Sum ( Rev_t PurchaseProb_t retentionProb_t/discountRate_t)
But, when I calculate the CLV for each customer and total it, it does not add up to total revenue. Any thoughts.
