detectseparation vs yahoofinancer: at a glance
What is detectseparation?
A diagnostic package that generalized past its own name, then learned to say which kind of separation it found
detectseparation identifies separation and infinite estimates in binomial-response GLMs — the condition where maximum likelihood estimates diverge and standard software reports large coefficients with enormous standard errors instead of an error. Version 0.3 was the structural turn: detect_infinite_estimates() became the general method covering log, logit, probit and cauchit links, with detect_separation() demoted to a wrapper around it. Version 0.4 in April 2026 adds the ability to distinguish complete from quasi-complete separation via separation_type.
What is yahoofinancer?
A Yahoo Finance client that spent four years chasing API drift before adding bulk retrieval
yahoofinancer wraps the Yahoo Finance API for R. Its first four releases are almost entirely repair work: 0.2.0 existed only to absorb upstream API changes, 0.3.0 and 0.4.0 fixed row mismatches, a wrong quote endpoint, a broken options call, and valuation columns returning identical values. Version 0.5.0 in June 2026 is the first release to add capability rather than restore it, introducing a Tickers class that fetches pricing, valuation and history for a vector of symbols in one call.

◆ Current state
detectseparation identifies separation and infinite estimates in binomial-response GLMs — the condition where maximum likelihood estimates diverge and standard software reports large coefficients with enormous standard errors instead of an error. Version 0.3 was the structural turn: detect_infinite_estimates() became the general method covering log, logit, probit and cauchit links, with detect_separation() demoted to a wrapper around it. Version 0.4 in April 2026 adds the ability to distinguish complete from quasi-complete separation via separation_type.
◆ Where it's heading
The package has been generalizing steadily — first past its own framing, since separation is one case of infinite estimates rather than the whole problem, and now toward finer classification of what it detects. The distinction 0.4 adds is practically useful because complete and quasi-complete separation call for different responses. Release intervals are long, roughly two to four years, which fits a diagnostic tool whose underlying theory is settled.
◆ Prediction
With link coverage broad and separation now classified by type, further work is more likely to refine reporting than to extend detection to new model families.

◆ Current state
yahoofinancer wraps the Yahoo Finance API for R. Its first four releases are almost entirely repair work: 0.2.0 existed only to absorb upstream API changes, 0.3.0 and 0.4.0 fixed row mismatches, a wrong quote endpoint, a broken options call, and valuation columns returning identical values. Version 0.5.0 in June 2026 is the first release to add capability rather than restore it, introducing a Tickers class that fetches pricing, valuation and history for a vector of symbols in one call.
◆ Where it's heading
The package is moving from single-asset lookups to portfolio-scale retrieval, and doing so without disturbing the existing path — the original Ticker class stays for single-asset deep dives while Tickers handles bulk. That parallel-class approach avoids a breaking change, but it means the package now carries two object models for the same data. The dependence on an undocumented upstream API remains the structural risk: two of the five releases here exist purely because Yahoo changed something.
◆ Prediction
Further breakage-driven patches are the safest expectation given the history, with any new work likely extending the Tickers class to the remaining single-ticker endpoints.
