Covariance-Insured Screening [article]

Kevin He, Jian Kang, Hyokyoung Grace Hong, Ji Zhu, Yanming Li, Huazhen Lin, Han Xu, Yi Li
2018 arXiv   pre-print
By incorporating the inter-feature dependence, we propose a covariance-insured screening methodology to identify predictors that are jointly informative but only marginally weakly associated with outcomes  ...  However, existing screening methods, which typically ignore correlation information, are likely to miss these weak signals.  ...  Discussion We have developed a covariance-insured screening method for ultrahigh-dimensional variables.  ...

After adjusting for covariates, private insurance and low deductible was significantly associated with higher prevalence of CRC testing, indicating that waiving the deductible could increase CRC screening  ...  Both colonoscopy and fecal occult blood test (FOBT) are commonly used for colorectal cancer (CRC) screening, but colonoscopy costs much more than FOBT.  ...  After adjusting for covariates, private insurance and low deductible were significantly associated with higher prevalence of CRC testing, indicating that waiving the deductible could increase CRC screening  ...

Investigating reversals of association for utilization of recent mammography among Hispanic and Non-Hispanic Black women

William Rakowski, Melissa A. Clark, Michelle L. Rogers, Sherry Weitzen
2009 Cancer Causes and Control  
Conclusions-Reversed associations found in adjusted analyses present a challenge for interpretation, but could also denote success of programs to increase screening rates.  ...  Insurance status was dichotomized as: non-insured versus insured (reference group).  ...  The six covariates in-common across all surveys were: age, income, education, insurance status, marital status, and Census region of the country.  ...
