Challenge

The Challenge

The objective was to determine whether huq footfall and dwell-time signals could accurately predict Walmart US quarterly net sales. The work had to control for noisy observations, changing panel size, seasonality and lookahead bias before the output could be useful to analysts and investors.

Create a demand proxy

Transform store visits and dwell behaviour into a signal that reflected consumer spending.

Control data noise

Remove dwell outliers, normalise panel growth and account for weekdays, weekends and holidays.

Validate unseen performance

Separate training and testing periods and select parameters without introducing lookahead bias.

The Solution

huq provided a live behavioural intelligence layer that unified movement trends, catchment visibility, and district benchmarking into a single platform.

Movement Intelligence

Live visibility into visitor activity and engagement patterns.

Demand forecasting

Demand Forecasting

Turn mobility and location signals into timely estimates of customer demand.

Data validation and research

Data Validation & Research

Validate mobility evidence and apply it in robust academic, commercial or policy research.

District Benchmarking

Compare commercial performance across multiple urban environments.

CASE STUDY OVERVIEW

huq used Walmart mobility signals to predict quarterly US net sales and validate a footfall-derived demand model.

huq matched enriched Walmart store-visit data with the Walmart US net-sales segment. Dwell observations were grouped into visits, filtered for outliers and converted into a normalised demand signal that respected panel growth and seasonality.

Case study highlights

  • Structured validation: Seventeen quarters were divided chronologically into 12 training and five test periods.
  • Signal engineering: Visit duration, dwell thresholds and normalisation rules captured behavioural nuance.
  • Large-scale parameter search: More than 750,000 candidate signal combinations were evaluated.
  • Independent test: Non-negative least-squares regression was assessed against previously unseen net-sales results.

The selected mobility signal closely tracked reported sales, demonstrating how location evidence can support high-frequency demand research.
