I modeled a multilevel distribution of three dimensional arrays using a Bayesian approach assuming a separable covariance structure that is the sum of a set of Kronecker products. The goal was to find patterns in the covariance of the survey participantâ€™s responses across quality measures and years to enhance public reporting and quality monitoring.

APPM 1350  Calculus 1 for Engineers
Primary Instructor

Fall 2020
Topics in analytical geometry and calculus including limits, rates of change of functions, derivatives and integrals of algebraic and transcendental functions, applications of differentiations and integration. Students who have already earned college credit for calculus 1 are eligible to enroll in this course if they want to solidify their knowledge base in calculus 1. For more information about the math placement referred to in the Enrollment Requirements, contact your academic advisor. Degree credit not granted for this course and APPM 1345 or ECON 1088 or MATH 1081 or MATH 1300 or MATH 1310 or MATH 1330.
APPM 3570  Applied Probability
Primary Instructor

Spring 2021 / Fall 2021
Studies axioms, counting formulas, conditional probability, independence, random variables, continuous and discrete distribution, expectation, joint distributions, moment generating functions, law of large numbers and the central limit theorem. Degree credit not granted for this course and ECEN 3810 or MATH 4510. Same as STAT 3100.
