Gestational Age Relationship Analysis (vs. `gestational_age_weeks`)¶

Investigating modeling approach for gestational age.

`gestational_age_weeks` Distribution¶

Summary:

	`count`	`mean`	`std`	`min`	`25%`	`50%`	`75%`	`max`
`gestational_age_weeks`	228	28.5088	2.17817	23	27	29	31	31

Distribution of gestational_age_weeks values.

Testing models for gestational_age_weeks predicting time_to_fof.

`Model`	`R²`	`CV R² (mean)`	`CV R² (std)`	`p-value (vs simpler)`
Linear	0.0857	-0.0342	0.0545	N/A
Quadratic	0.0861	-0.0524	0.0617	0.7425
Ordinal (Rounded Weeks)	0.0857	-0.0342	0.0545	0.0000

Linear, Quadratic, and Ordinal (Rounded Weeks) fits.

Best fit based on statistical criteria for gestational_age_weeks: Ordinal (R²=0.086) - Higher or equivalent R² compared to linear (R²=0.086)
