which method of regression should i use to find crude death rate rate when is incidence rate ratio used in linear regression can r use crude death rate data is incidence rate ratio linear regression how to calculate irr in r what is irr in r statistics if i log mortality rate what does irr mean how do you calculate incidence rate ratio can you log the crude rate of a crude death does poisson show the incidence rate ratio can you find irr in poisson what is incidence rate ratio in r why not use poisson data does poisson use incidence rate data can you find incidence rate ratio in r does reglet use poisson data can i use poisson to calculate irr in r if poisson is log-transformed, what is the irr can you use poisson data to find incidence rate how to get crude rate data in r
