AF (version 0.1.5)

Model-Based Estimation of Confounder-Adjusted Attributable Fractions

Description

Estimates the attributable fraction in different sampling designs adjusted for measured confounders using logistic regression (cross-sectional and case-control designs), conditional logistic regression (matched case-control design), Cox proportional hazard regression (cohort design with time-to- event outcome), gamma-frailty model with a Weibull baseline hazard and instrumental variables analysis. An exploration of the AF with a genetic exposure can be found in the package 'AFheritability' Dahlqwist E et al. (2019) .

Functions in AF (0.1.5)

Plot function for objects of class "AF" from the function AFcoxph or AFparfrailty.

Attributable fraction estimation based on a logistic regression model from a glm object (commonly used for cross-sectional or case-control sampling designs).

Case-control study on oesophageal cancer in Chinese Singapore men.

Cohort study on breast cancer patients from the Netherlands.

Attributable fraction function based on a Cox Proportional Hazard regression model as a coxph object (commonly used for cohort sampling designs with time-to-event outcomes).

Attributable fraction for mached and non-matched case-control sampling designs. NOTE! Deprecated function. Use AFglm (for unmatched case-control studies) or AFclogit (for matched case-control studies).

Attributable fraction function for cohort sampling designs with time-to-event outcomes. NOTE! Deprecated function. Use AFcoxph.

Attributable fraction function based on Instrumental Variables (IV) regression as an ivglm object in the ivtools package.

Attributable fraction estimation based on a conditional logistic regression model as a clogit object (commonly used for matched case-control sampling designs).

Attributable fraction for cross-sectional sampling designs. NOTE! Deprecated function. Use AFglm.

Attributable fraction function based on a Weibull gamma-frailty model as a parfrailty object (commonly used for cohort sampling family designs with time-to-event outcomes).

Birthweight data clustered on the mother.

Summary function for objects of class "AF".
