Developing new mapping algorithms
Using the CYPHP cohort, we investigated whether we could improve the predictive accuracy of the mapping algorithms. Our full study sample was divided into estimation (80%) and validation (20%) samples, using random sampling without replacement. We considered the following model specifications for the total, dimension, and item scores based on previous mapping development papers [Stepwise variable selection using the OLS estimator and based on Akaike Information Criterion (AIC) was used to identify the final specification for each of the three equations [
