Spontaneous Abortion and Termination Gestational Age Algorithms in Healthcare Utilization Database

In this study, we developed and validated two new claims-based gestational age algorithms for spontaneous abortions and terminations, using random forests. Please cite the paper if you implemented any of the following algorithms in your study. Algorithm 3.e – Random Forests, mtry=p/3, Boruta selected variables Algorithm 3.f – Random Forests, mtry=p/2, Boruta selected variables Please follow the cohort creation in the published paper on the development and validation of the algorithms and use the implementation guide \"READ ME_Gestational Age Algorithm Implementation Guide\" to implement the gestational age algorithm properly in your database.
