内容提要:

In economics, marketing research and business management, it is important to estimate the temporal trend of sales of products or the market share of a business during a period of time. In public health likewise, it is crucial to estimate the temporal trend of chronic disease (cancer, cardiovascular diseases, etc.) mortality rates.  Often the sales of products vary with the age of consumers (e.g. sales of cosmetic products or life insurance policies), and the mortality rate varies with the age of patients (e.g. mortality rate of breast cancer), thus are reported by age group. More importantly, they also vary largely with the cohort (or generation) effect, which shows large difference between the older generations and younger generations. This presents a major challenge in statistical modeling - the identifiability problem in regression models with linearly dependent covariates, which has perplexed the statistical community for decades.  I will present this complicated problem using simple graphical method, and present the most recent advances in addressing this identifiability problem. I will also demonstrate some novel methods with economics, public health and insurance policy purchase data.
