It was simple sufficient to quantify the connection between two numerical measurements — say, how top correlates to revenue degree. However what about nonnumerical classes, like race and occupation?
There have been statistical strategies out there from the pure sciences, like physics, however they have been crude and imprecise when utilized to inhabitants information. On the similar time, postwar America was seeing a increase in information of all types: Census analysis, public polls, advertising surveys and mountains of data gleaned from the hundreds of thousands of males who had served in World Warfare II.
It was a gold mine for sociologists, and Professor Goodman gave them the instruments to dig into it.

Over the course of his practically 70-year profession — he didn’t retire till 2017, when he was 89 — he developed not solely the framework for analyzing enormous units of categorical information, however the statistical devices to indicate relationships amongst these classes.
His work had a right away and lasting affect on the research of topics like poverty and social mobility. And as subtle quantitative evaluation migrated into different fields, so did his strategies: Immediately his affect will be felt in areas as distinct as administration research and laptop science, the place a few of his statistical modeling instruments are being utilized to machine studying.
Professor Goodman died on Dec. 22 in a hospital in Berkeley, Calif. He was 92. The trigger was problems of Covid-19, his son Andy stated.
“Leo remodeled the way in which categorical information is analyzed,” stated Yu Xie, a sociologist at Princeton. “He was a genius, a legend.”

He married Ann Davidow, a kids’s e book writer, in 1960, simply earlier than the couple moved to Cambridge College, in England, the place Professor Goodman had a fellowship.

He moved to the College of California, Berkeley in 1986, a number of years after creating a uncommon type of most cancers. His medical doctors wished to amputate his legs, however he dug into the medical literature and found that chemotherapy and new types of remedy might save them.
Although the medical doctors in the end eliminated three of his 4 quadriceps, he was capable of stroll with barely a limp after a number of years of bodily remedy. When colleagues would go him on campus and ask how he was, he would reply, “Not good” — including, after a beat, “Terrific!”
