####
Algebra 1

I received A grades in high school first year algebra, and I tutored high school students in first year algebra.

####
Algebra 2

I received A grades in high school second year algebra, and I tutored high school students and adults in high school second year algebra.

####
Biology

I achieved A grades in biology in high school, and I tutored biology in high school. Subsequent, I studied 2 semesters of physiological psychology as a college psychology major. Since receiving my PhD degree in statistics, I have worked with researchers in biological psychiatry.

####
Calculus

I studied caluclus for 3 semesters at Harvey Mudd College. I studied material depending on calculus such as: physics and chemistry at Harvey Mudd College; probability and statistics at the University of Missouri and Carnegie-Mellon University.

####
Chemistry

I tutored chemisty in high school. I achieved a score of 760 on the ETS Chemistry Achievement Test. I studied chemistry for two semesters at Harvey Mudd College.

####
Trigonometry

I received A grades in trigonometry in high school, and I tutored trigonometry in high school. I followed that up with collegiate course work that depends on trigonometry, such as calculus (differentiation and integration of trigonometric functions); and probability theory (characteristic functions, also called Fourier transforms.)

####
Statistics

I achieved a PhD degree in statistics. I have lectured (and graded) at all undergraduate levels. I have tutored in statistics, including behavioral science majors, statistics majors, and foreign students.

####
Psychology

My bachelor's degree was in psychology. I did graduate study in psychology, directed student research, collaborated in research and published papers in psychology journals. Since receiving my PhD degree in statistics I have worked with researchers in psychiatry and psychology.

####
SPSS

I have tutored and taught statistical data analysis to graduate students in clinical psychology. I tutored them in SPSS , and they learned well enough to publish and defend their work without my presence at test time.

####
Probability

I studied probability as and undergraduate student at the University of Missouri and Carnegie-Mellon University. I tutored students in probability, including behavioral science majors and foreign students.

####
Differential Equations

I have experience fitting differential equation models to biological and behavioral phenomena, in Pharmacokinetics, Pharmacodynamics, Neurological Modeling, and Biological Rhythms. My experience is mostly with numerical solutions of systems of non-linear differential equations.

####
SAS

In about 1984, the Statistics Department at Carnegie-Mellon University bought its own VAX 11/780 computer. Shortly after that, the licensed SAS for the VAX. I was the most experienced SAS user in the department (I think I was the only SAS user), so the Chairman invited me to give lectures to the Department, and I did that: I gave 2 lectures 2 hours in length. I illustrated the Link-Return statements in the Data step, the Macro language, the built-in statistical functions, sorting, and match-merging...

####
Biostatistics

I have a PhD degree in statistics. I have worked with university and industry scientists analyzing data from simple and complex experiments on people and animals. I have published papers. I have written grant proposals and IRB submissions.

####
Econometrics

I have experience with the data analytic techniques used in econometrics, such as multivariate time series (vector autoregressive processes, "Granger Causality", conditional heteroscedasticity), and rhythmicities (seasonal effects.) Also other multivariate techniques such as multiple linear regression and multiple logistic regression, discriminant analysis and clustering (market segmentation), and panel analyses.

####
Linear Algebra

In college I took the usual course in linear algebra, and I used the material (some of it) repeatedly in graduate training and in writing my PhD thesis -- e.g., taking the derivative of the determinant of a symmetric matrix with respect to (arguments of) the elements of the matrix (when the elements are functions of a small number of parameters).
