aspre {OptHoldoutSize}

Computes ASPRE score

Description

Computes ASPRE model prediction on a matrix X of covariates

Full ASPRE model from https://www.nejm.org/doi/suppl/10.1056/NEJMoa1704559/suppl_file/nejmoa1704559_appendix.pdf

Model is to predict gestational age at PE; that is, a higher score indicates a lower PE risk, so coefficients are negated for model to predict PE risk.

Usage

aspre(X)

Arguments

X

matrix, assumed to be output of sim_random_aspre with parameter params=params_aspre and transformed using add_aspre_interactions

Value

vector of scores.

Examples

# Load ASPRE related data
data(params_aspre)

X=sim_random_aspre(1000,params_aspre)
Xnew=add_aspre_interactions(X)

aspre_score=aspre(Xnew)

plot(density(aspre_score))
