# What is a beta geometric model?

## What is a beta geometric model?

The beta-geometric (BG) distribution is a robust simple model for characterizing and forecasting the length of a customer’s relationship with a firm in a contractual setting. Consider a company with a subscription-based business model that acquired 1000 customers (on annual contracts) at the beginning of Year 1.

**What is sBG model?**

The shifted-beta-geometric (sBG) model makes two assumptions: Each customer has a constant churn probability θ. You can think of this as the customer flipping a weighted coin (with probability of tails = θ) at the end of every subscription period, and they cancel their membership if the coin lands tails.

### How do you model retention?

To calculate retention rate, divide your active users that continue their subscriptions at the end of a given period by the total number of active users you had at the beginning of that time period.

**How do you calculate residual lifetime value?**

Residual lifetime value is the amount of additional value we expect to collect from a customer over a given time period. From here, CLV is easy to get to — just add the sum of each customer’s past purchases to their RLV.

## What is Pareto NBD model?

The Pareto/NBD aims to model whether or not customers are alive and, if alive, how frequently they purchase. Customers purchase according to a Poisson process while alive. Customer lifetimes are distributed according to an exponential distribution.

**What is Gamma Gamma model?**

The properties of Gamma-Gamma model are: Monetary value of users’ transactions is random around their mean transaction value. Mean transaction value varies across users but doesn’t vary for an individual user over time. Mean transaction values is Gamma distributed across customers.

### What is retention modeling?

Retention models utilize historical first-party data to predict future behavior. If purchase data is not available, retention models can be built using other first-party data sources, including product registration, coupon redemption, form submissions, and consumer engagement data.

**How do you measure patient retention?**

Find out how many customers you have at the end of a given period (week, month, or quarter). Subtract the number of new customers you’ve acquired over that time. Divide by the number of customers you had at the beginning of that period. Then, multiply that by one hundred.

## What is the CLV formula?

The Simple CLV Formula The most basic way to determine CLV is to add up the revenue earned from a customer (annual revenue multiplied by the average customer lifespan) minus the initial cost of acquiring them.

**What is the formula for customer lifetime value?**

The simplest formula for measuring customer lifetime value is the average order total multiplied by the average number of purchases in a year multiplied by average retention time in years. This provides the average lifetime value of a customer based on existing data.

### What does the Pareto Principle State?

The Pareto Principle states that 80% of consequences come from 20% of the causes. The principle, which was derived from the imbalance of land ownership in Italy, is commonly used to illustrate the notion that not things are equal, and the minority owns the majority.

**What is a customer lifetime value CLV and how is it estimated?**

Key Takeaways. Customer lifetime value (CLV) is a measure of the average customer’s revenue generated over their entire relationship with a company. Comparing CLV to customer acquisition cost is a quick method of estimating a customer’s profitability and the business’s potential for long-term growth.
