Jul 1, 2025July 2025 monthly summary for ONSdigital/monthly-business-survey-results focusing on key accomplishments, business value, and technical achievements. In July, delivered the Weighted Growth Rates Calculation feature for the Monthly Business Survey Results repo. Introduced weighted_target by weighting adjustedresponse with design_weight, outlier_weight, and calibration_factor, and updated the growth rates aggregation to use weighted_target instead of the raw target. This change enhances accuracy and comparability of growth metrics across cohorts and reduces susceptibility to extreme values. The work is tracked under commit b3e72a738bd0baf6807e9e7c4a3f8922372df7bc (weighted version of target variable in growth rates output and corrections) linked to PR (#251).
