This package provides functions for standardizing neuropsychological test results using T-scores adjusted for age, sex, and education. It is an extension of the ntrs package.
The main function, std_using_tscores(), takes raw scores from various neuropsychological tests and applies the appropriate T-score adjustments based on demographic factors. The package includes specific implementations for different tests, such as the ANIMALS test, and ensures that the standardized scores are within a valid range.
