To explore the feature importance of e-consumers behaviour and perceived risk in retailing. Also, to classify retail repurchase intentions and risk-taking tendencies using the Random Forest (RF) model.
Data were collected from 500 retail digital buyers. The classification model was designed using the RF algorithm, which consists of four stages: data acquisition, data analysis and feature selection, model development and random search on parameters. The proposed model was confirmed using key metrics.
In the theory of planned behaviour interpretive lens, factors such as product features, clarity, product image, feedback, advertisements and product information explain the e-consumers buying intentions. Also, the study classifies the risk features, which are in line with perceived risk theory (explains why certain beliefs influence buying intention under risk). The proposed RF model has an area under curve (AUC) value of 0.97 (repurchase intention) and an AUC value (willingness to take risk) of 0.90, representing excellent discriminative power.
The joint modelling of e-consumers' buying behaviour and perceived risk features offers predictive decision support with enhanced capability to personalise consumer engagement to digital retailers.
Research offers data-driven decisions for segmentation, personalisation and risk-based strategy for retailing, which positively impact e-consumers' decision-making.
