Office of Program Evaluations Statistical Research Assistant
Provided statistical item analysis on surveys used to evaluate education programs
implemented throughout public schools in South Carolina. Used statistical software such
as SAS and R to provide summary reports and informative statistics on how well their
surveys measure program performance.
Academic Research (“^” indicates completed; “+” marks ongoing)
^ Smith, W.Z. (2014, May) Can Computer Algorithms Guess Your Age and Gender? An
independent study under the supervision of Dr. Cuixian Chen that evaluated the
accuracy of two well-known classification algorithms in facial recognition: Linear
Discriminant Analysis (LDA) and Mixture Discriminant Analysis (MDA). These
classifiers were applied to an archive of Active Appearance Models (AAM(s)) –
obtained from the 1002 images of the FG-NET database. In using both 5- fold and
leave-one-person-out cross-validation to obtain each algorithm, an accuracy rating
for each algorithm for each respective cross-validation technique, in respect to
their ability to estimate a person’s age and gender, was obtained and evaluated.
Recognized by University of North Carolina’s Board of Trustees for quality of
work and creativity.
^ Smith, W.Z. (2015, May) Questionnaire Refinement in Neuropsychological
Assessments. Honors Thesis conducted under the supervision of Dr. Cuixian
Chen and Dr.Yishi Wang that analyzes Neuropsychological Assessments given
to veterans such as the Trauma Symptom Inventory (TSI) and the Minnesota
Multiphasic Personality Inventory-2 (MMPI-2). By utilizing the Item Response
Theory (IRT) model on these tests, multiple statistical analyses provided insight
into the underlying characteristics of the TSI and MMPI: item difficulty, item
discrimination, and local dependency. The TSI and MMPI are time consuming,
therefore a shorter test with tailored assessments are needed. From the IRT
model, the selected subset of items will provide equally as informative tests as
the longer version, while still maximizing precision along all segments.
