Aaru alternatives

Aaru publishes TVD and MAE on 2,993 questions (aaru.com, checked October 2, 2026) and a Spearman rank correlation plus an average difference on 53 questions in a blinded EY wealth study. On the calibrated 50-state benchmark, the average miss is 7.07 points on the best 80% of 1,521 scored questions, and 10.02 points across all of them. Alternatives should be scored on the metric they publish, the sample they name, and how a buyer starts.

What you are actually replacing

Aaru's public pages describe simulated populations for decisions, grounded in real-world behavior and outcomes. The EY study is a wealth-research recreation. If your use case is a U.S. consumer panel with crosstabs, ask every vendor for a number on that instrument. If the job is behavioral simulation before a decision, Aaru publishes that product (aaru.com, checked October 2, 2026).

Worked example: keep each metric in its own unit

TVD and MAE on 2,993 questions, a rank correlation on 53 questions, and Lewsearch's Calibrated 50-state benchmark: 7.07 points on the best 80% of 1,521 scored questions, 10.02 across all of them. are three statistics. Simile's 7,000+ evaluations are a volume claim. Do not average them.

FAQ

What does Aaru publish that an alternative should be ready to match in specificity?
A homepage metric: TVD and MAE on 2,993 questions (aaru.com, checked October 2, 2026). A named study: a Spearman rank correlation and an average difference on 53 questions in a blinded EY wealth study. Ask any alternative for the instrument, the n, and the link.
Does Simile publish the same kind of number?
Simile publishes 7,000+ evaluations and does not publish a percentage-point MAE (simile.com, checked October 2, 2026). It cites a 1,000-person paper on the homepage. It does not print a price there.
Which alternative publishes a public miss and scopes the engagement on a call?
On the calibrated 50-state benchmark, the average miss is 7.07 points on the best 80% of 1,521 scored questions, and 10.02 points across all of them. Pricing is scoped to your audiences and study volume on a short call. Your first qualified U.S. consumer Blind Challenge is free. Enterprise teams start with an 8-week pilot that rolls into an annual engagement. Aaru and Simile do not print price lists on the homepages linked below.
Can I treat a rank correlation as percent correct?
No. A rank correlation is a different unit from mean absolute error, and a different unit from a share of questions scored correct.
