Expertise you can actually understand
Plenty of firms can run a model. Fewer can tell you what it means, whether it's the right one, and how to explain it to a reviewer, a board, or a grant committee. That's the gap we fill.
Right method, first time
We match the model to your question and data, not to habit.
Plain-language results
Findings explained so any stakeholder can act on them.
Fast turnarounds
Personalized service without the agency backlog.
Senior expertise
You work with experienced statisticians, start to finish.
A clear path from question to answer
Free consult
A short call to understand your question, data, and deadline.
Scoped plan
A clear proposal with methods, timeline, and a fixed quote.
Analysis
We do the work — and check in so there are no surprises.
Handoff
Results, figures, and reproducible code, explained clearly.
Trusted by researchers who don't cut corners
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.
DASS did a fantastic job. They were patient, clear about the coding, and very responsive to my emails. They took the time to understand the overall goal before proceeding with each step. Highly recommend.
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.
DASS started from a simple frustration: too much good research stalls because the statistics are done to it, not with it. We built a practice where you talk directly to the statistician doing the work — someone who cares as much about explaining the result as computing it.
Statisticians who speak human
You work directly with senior methodologists who stay hands-on with your project from first call to final handoff.
PhD in psychometrics and a Harvard Strategic Data Fellow with 15+ years across NSF-, IES-, and foundation-funded research — from randomized trials at 22 colleges to healthcare and access-to-justice work. Today he also works as a Senior Data Scientist building AI products.
Associate Professor at UMass Boston and PI on ~$5M in grants, with research cited over 2,000 times. She blends rigorous qualitative and quantitative methods to answer the questions numbers alone can't.
Frequently asked questions
What does the free consult actually involve?
A short call to understand your question, data, and deadline. You leave with a plan — a scoped proposal with methods, timeline, and a fixed quote — whether or not you end up hiring us.
How much does statistical consulting cost?
It depends on scope, so we don't publish a fixed price list — the free consult produces a scoped quote for your specific project. If you want context before that call, we've written about how statistical consulting is typically priced.
How long does a project take?
It depends on scope and your deadline — a real timeline is part of the scoped plan you get from the free consult, not a generic estimate. We reply to initial inquiries within one business day.
Is my data kept confidential?
Yes. Don't include sensitive or identifiable participant, patient, or student data in an initial inquiry — secure file-transfer arrangements are set up after engagement, once there's a signed agreement in place.
Do you only work with academic researchers?
No. Academics and funded researchers are a core audience, but we also work with non-profits and foundations, healthcare and clinical research, legal and public-policy research, and AI and technology startups.
What statistical software do you use?
R. Every deliverable includes reproducible R code you keep, and we also run hands-on R workshops for teams who want to build in-house capacity rather than depend on us indefinitely.
Can I hire you for just one part of a project?
Yes — a single power analysis, a single round of analysis, or a specific methods section. Engage us for one analysis or as an ongoing methods partner across the full lifecycle of a project; either is a normal engagement, not an exception.
I'm not sure what kind of help I need — is that okay?
That's exactly what the free 30-minute consult is for. Bring the problem, not a finished plan, and leave with one.
