I have been continuously engaged in the development of new statistical methodologies to address these limitations in various directions. These methods have innovated ways to assemble and analyze diverse forms of temporally ordered data. Recent empirical applications of these methods have produced new evidence for long-standing questions and suggested new questions to ask in interdisciplinary population research on aging.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-cover is-light\"><img loading=\"lazy\" decoding=\"async\" width=\"1254\" height=\"1254\" class=\"wp-block-cover__image-background wp-image-214 size-full\" alt=\"\" src=\"https:\/\/sites.nd.edu\/yang-c-yang\/files\/2026\/08\/ChatGPT-Image-21-ago-2026-13_16_09-1-1.png\" data-object-fit=\"cover\" srcset=\"https:\/\/sites.nd.edu\/yang-c-yang\/files\/2026\/08\/ChatGPT-Image-21-ago-2026-13_16_09-1-1.png 1254w, https:\/\/sites.nd.edu\/yang-c-yang\/files\/2026\/08\/ChatGPT-Image-21-ago-2026-13_16_09-1-1-300x300.png 300w, https:\/\/sites.nd.edu\/yang-c-yang\/files\/2026\/08\/ChatGPT-Image-21-ago-2026-13_16_09-1-1-1024x1024.png 1024w, https:\/\/sites.nd.edu\/yang-c-yang\/files\/2026\/08\/ChatGPT-Image-21-ago-2026-13_16_09-1-1-150x150.png 150w, https:\/\/sites.nd.edu\/yang-c-yang\/files\/2026\/08\/ChatGPT-Image-21-ago-2026-13_16_09-1-1-768x768.png 768w\" sizes=\"auto, (max-width: 1254px) 100vw, 1254px\" \/><span aria-hidden=\"true\" class=\"wp-block-cover__background has-background-dim\" style=\"background-color:#ece0cc\"><\/span><div class=\"wp-block-cover__inner-container is-layout-constrained wp-block-cover-is-layout-constrained\">\n<p class=\"has-text-align-center wp-block-paragraph\"><strong><a href=\"https:\/\/sites.nd.edu\/yang-c-yang\/research\/social-relationships-and-health\/\" data-type=\"page\" data-id=\"85\">Age-Period-Cohort (APC) Analysis<\/a><\/strong><br><\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-cover is-light\"><img loading=\"lazy\" decoding=\"async\" width=\"1254\" height=\"1254\" class=\"wp-block-cover__image-background wp-image-221 size-full\" alt=\"\" src=\"https:\/\/sites.nd.edu\/yang-c-yang\/files\/2026\/08\/ChatGPT-Image-21-ago-2026-13_24_23-1.png\" data-object-fit=\"cover\" srcset=\"https:\/\/sites.nd.edu\/yang-c-yang\/files\/2026\/08\/ChatGPT-Image-21-ago-2026-13_24_23-1.png 1254w, https:\/\/sites.nd.edu\/yang-c-yang\/files\/2026\/08\/ChatGPT-Image-21-ago-2026-13_24_23-1-300x300.png 300w, https:\/\/sites.nd.edu\/yang-c-yang\/files\/2026\/08\/ChatGPT-Image-21-ago-2026-13_24_23-1-1024x1024.png 1024w, https:\/\/sites.nd.edu\/yang-c-yang\/files\/2026\/08\/ChatGPT-Image-21-ago-2026-13_24_23-1-150x150.png 150w, https:\/\/sites.nd.edu\/yang-c-yang\/files\/2026\/08\/ChatGPT-Image-21-ago-2026-13_24_23-1-768x768.png 768w\" sizes=\"auto, (max-width: 1254px) 100vw, 1254px\" \/><span aria-hidden=\"true\" class=\"wp-block-cover__background has-background-dim\" style=\"background-color:#e6d9c4\"><\/span><div class=\"wp-block-cover__inner-container is-layout-constrained wp-block-cover-is-layout-constrained\">\n<p class=\"has-text-align-center wp-block-paragraph\"><strong><a href=\"https:\/\/sites.nd.edu\/yang-c-yang\/research\/data-linkage-methods\/\" data-type=\"page\" data-id=\"138\">Data Linkage Methods<\/a><\/strong><\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><br><\/p>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Last updated on: <\/p>\n\n\n<div class=\"wp-block-post-date__modified-date wp-block-post-date\"><time datetime=\"2026-08-26T19:52:03+00:00\">August 26, 2026<\/time><\/div>\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Studies of time-related change are key to understanding the process and dynamics of aging but are often subject to data and methodological limitations.
