How do predictive analytics work?

Predictive analytics has four main steps:

Data Collection

Data collection involves gathering relevant data from various sources. You could gather data from various sources. These include: customer databases, transaction records, social media interactions, and sensor data. The more diverse and comprehensive the data, the better the predictions are likely to be. During data collection, it’s important to ensure data quality and compatibility. You will need to undertake data cleaning. Data cleaning removes any errors or inconsistencies. During data cleaning, you also set out the data in a format that’s easy to analyze. Data cleansing techniques include removing duplicates, handling missing values, and standardizing data formats. Data privacy and security are also important during this phase. Ensure you adhere to privacy regulations and implement robust security measures.

Data Preparation

Data preparation is where your raw data is set out in a suitable format for predictive analytics models. Data preparation includes a range of tasks. These include: data cleaning, data integration, feature engineering, and data normalization. Data cleaning involves removing any outliers, inconsistencies, or errors in the data. Data integration involves combining data from different sources into a unified dataset. Feature engineering is the process of creating new features or transforming existing features. Data normalization is the process of scaling the data to a common range or distribution.

Model Building

Model building is the heart of predictive analytics. Model building involves selecting and applying statistical algorithms and machine learning techniques. Your goal is to build an effective predictive model. An effective predictive model learns from historical data. An effective predictive model then makes accurate predictions on new, unseen data. Your choice of predictive modeling technique will depend on the nature of the problem you’re trying to solve. Your predictive modeling choice is also determined by your available data. You will choose a model based on your desired level of accuracy. During model building, you will split your data into training data sets and testing data sets.

Training data is used to train your predictive analytics model. Testing data is used to evaluate your predictive analytics model’s performance. During model building, you will also set and tune parameters.

Parameter tuning involves testing different configurations of your model. You may use various techniques, like cross-validation or grid search.
