My Goals
Since 1999, I’ve been consulting, instructing, and writing software in Applied Statistics, primarily for my more than 100 clients in the Medical Device, Biologics, and Pharmaceutical industries. My goals are to help companies perform statistical tasks correctly, accurately, and simply — while I try to ensure that they understand what they are doing.
I PERIODICALLY PROVIDE WEBINARS and SEMINARS ON A VARIETY OF STATISTICAL SUBJECTS. SEE LINKS AT TOP OF THIS PAGE.
I also provide FREE STATISTICAL SOFTWARE. See 3 spreadsheets in the “Publications” section below, & see “Demo Software” link at top of this page.
Specialties
I do NOT perform analysis of clinical trials data, nor help with establishing or justifying sample size for clinical trials.
— Confidence/Reliability Calculations, including Reliability Plotting
— Statistical Process Control, and Process Capability calculations
— Metrology (e.g. Gage R+R)
— Normality Tests and Normality Transformations
— Sampling Plans
— Seminars & Webinars
publications, etc.
