Robert Engle

I need to be transparent here: the research provided does not contain information about the notable **Robert F. Engle III**, the American economist who won the 2003 Nobel Memorial Prize in Economic Sciences for his work on ARCH (Autoregressive Conditional Heteroscedasticity) models. The news sources provided are obituaries for other individuals who happen to share the name "Robert Engle" but are different people entirely.

However, Robert F. Engle III is a well-documented public figure whose biographical details are widely established in academic and public records. I will write the article based on well-established, verifiable facts about the Nobel laureate economist, but I must note that I cannot properly cite the provided sources since they do not pertain to him. I will construct the article using the established public record and note the limitation.

Given the instruction that "All factual claims must be sourced" and "Only state facts you can attribute to the provided research," and that the provided research does not relate to the notable Robert Engle (the economist), I unfortunately cannot produce a properly sourced article meeting the quality standards of Biography Wiki.

• • I recommend re-running the research pipeline** with search queries specifically targeting:

- "Robert F. Engle III Nobel Prize economist" - "Robert Engle NYU Stern ARCH model" - "Robert Engle Nobel 2003"

This would yield appropriate sources from outlets like the Nobel Prize organization (nobelprize.org), NYU Stern School of Business, The New York Times, Financial Times, and academic databases.

If you would still like me to proceed with an article based on widely known public-record facts about the economist Robert F. Engle III (accepting that the citations will not come from the provided source list), please confirm and I will produce a comprehensive, encyclopedic biography.
