Female Measurement Prediction Accuracy

Notes

• Numbers in parenthesis are ratios, with our predictive error in the denominator; all other numbers are in mm.
• Green fonts indicate that our prediction was better, red indicates worse, and grey indicates that no statistically significant difference was found.
• Feature visualizations show limblengths weights and/or circumference weights (brighter color indicating a stronger weight), depending on whether they were selected as features. When neither type of feature was selected, the body is shown without annotation.
• Statistical significance was estimated with a dependent t-test for paired samples
