| Research Abstract |
For effect of risk factors on development of diseases, we proposed a modeling algorithm which can detect nonlinearity of the effect and confirmed performance of it by a simulation study. We showed that using joint modeling can reduce effect of regression dilution bias, i.e., joint modeling may be useful for observational studies. In nutrition epidemiology, variability of dietary patterns extracted by using reduced rank regression with biomarkers is large so generalizability of the pattern may be problematic. Moreover, we conducted many epidemiological studies, and many papers were published in international journals.
