For psychology researchers

Your model needs to satisfy a psych methodologist, not just run without errors.
One of our co-founders is one.

Statistical and methodological support for psychology research — multilevel modeling, SEM, psychometrics, and intervention-study design — from a team that includes a practicing psychology researcher, not just a statistician who occasionally sees psych data.

Co-founded by a psychologist

Dr. Kerrie Wilkins-Yel is an Associate Professor in counseling psychology (mental health and counseling) at UMass Boston, an NSF CAREER Fellow, and PI on ~$5M in grants studying STEM persistence and equity — cited over 2,000 times. When you work with DASS on a psychology study, you're not explaining your field to an outside statistician; you're working with someone who publishes in it.

I recruited Nedim for his analytical skills and research abilities. He brought very strong quantitative research skills and the interpersonal ability to work effectively with a wide range of people from diverse backgrounds. He excelled at ferreting out and interpreting information from multiple sources. My highest recommendation.

We had an unrealistically tight timeline, and Dr. Yel jumped in without hesitation — not only met the deadline, but delivered a little earlier than we anticipated. He took the time to understand the situation behind the data and the implications of every insight. We know who to go to for future work like this.
