Unlocking Actionable Transaction Insights: Weighted Averages for Accurate Predictions
Published: 2023-06-29 03:40:28

Imagine you are part of a multi-million dollar, multi-national company that provides financial services for small and medium enterprises across the continent. You want to provide your users with real-time information on the performance of transaction attempts from various finance institutions. This data will empower businesses to make informed decisions about when and how to carry out successful transactions.


The Challenge: Lack of Comprehensive Data

However, gathering data from all finance institutions is a daunting task. While you have access to a substantial amount of data generated on your platform, it's important to acknowledge that you don't have access to all the transaction data in real-time. This limitation hinders your goal of providing up-to-the-minute information.

Weighted Averages: A Statistical Approach for Actionable Insights
---
What if we could still provide a fairly accurate representation of the state of affairs, even without all the transaction data? This is where statistical analysis comes into play. By using a technique known as weighted averages, we can calculate the reliability of transactions performed by different financial institutions.

## Understanding Weighted Averages
Weighted averages involve assigning different weights to sets of transaction data to denote their relevance. The most recent data is given the highest weight, while older data receives lower weights. This approach ensures that we prioritize the most up-to-date information when assessing transaction reliability.

Let's break down the calculation process step-by-step:

1. Data Collection: Acquire the latest transaction data from your customers using methods like websockets, database integrations, or API connections.

2. Defining Relevance: Determine a specific time period within which the data is considered relevant. For example, let's choose a 20-minute interval. Any data older than 20 minutes will be considered less reliable.

3. Data Aggregation: Group the transaction data into sets based on a specific time interval. In our scenario, we'll use one-minute intervals. Each set will aggregate the successful and failed transactions for a particular financial institution, such as Acme Bank.

4. Assigning Weights: Assign weights to each set of data to denote relevance. We can use a descending scale where the most recent set receives the highest weight (e.g., 20) and the oldest set receives the lowest weight (e.g., 1).

5. Calculating Weighted Averages: Multiply the number of successful and failed transactions in each set by their respective weights. Then, sum up the weighted results for both successful and failed transactions.

6. Determining Success Rate: Calculate the success rate by dividing the sum of successful transactions by the sum of successful and failed transactions. This provides a reliable measure of transaction success likelihood.

## The Technicalities: Unveiling Transaction Insights
Now that we understand the importance of weighted averages in assessing transaction reliability, let's dive into the technical details. Don't worry; I'll guide you through the process with a friendly and approachable tone.

### Step 1: Acquiring the Latest Data
Before we can work our magic with weighted averages, we need to get our hands on the freshest transaction data. You already have a means of acquiring this data from your customers, whether it's through websockets, database connections, or APIs. This ensures you stay up to speed with the latest happenings.

### Step 2: Defining Relevance and Data Aggregation
To keep things organized, we'll define a specific time period that we consider relevant. Let's say we opt for a 20-minute interval, but feel free to adjust it to your preference. Within this timeframe, we'll break down the data into sets based on smaller intervals. For our scenario, one-minute intervals should do the trick.

### Step 3: Weighing the Importance
Now, here's where the magic happens. We assign weights to each set of data, indicating their significance. Think of it as giving priority to the cool kids on the block - the more recent the data, the higher the weight. We'll use a descending scale, where the most recent set receives the weight of 20, and the oldest set gets a weight of 1. This way, we ensure our analysis is based on the most up-to-date information.

### Step 4: Crunching the Numbers
With our sets of data and their respective weights in place, we're ready to crunch some numbers. Brace yourself; it's easier than it sounds! For each set, multiply the number of successful transactions by the corresponding weight and sum them up. We'll do the same for the failed transactions, but with a fixed weight of 1 since we're only interested in their occurrence.

### Step 5: Unveiling the Success Rate
Now, the moment of truth: the success rate calculation! Take the sum of successful transactions we just calculated and divide it by the sum of successful and failed transactions. Voila! That's your success rate - a reliable measure of the likelihood that a transaction will go smoothly within your platform and for your customers' customers.

## Empowering Users with Actionable Insights
You've done it! By employing this statistical approach, you're now equipped to provide your customers with actionable transaction insights, and you can provide your customers with valuable insights into transaction reliability. Armed with this information, businesses can make more informed decisions and develop strategies to optimize their financial operations. It's important to remember that these insights are specific to your platform and your customers' customers.
