new Learn article: using offsets

[topepo]

With the new tidymodels offsets package (offsetreg), I realize that we have not documented that this can already be done:

library(tidymodels)
library(offsetreg)
library(poissonreg)

us_deaths$offset <- log(us_deaths$population)

fit <- 
  poisson_reg() %>% 
  fit(deaths ~ gender + age_group + year + offset(offset), data = us_deaths)

tidy(fit)
#> # A tibble: 9 × 5
#>   term            estimate std.error statistic p.value
#>   <chr>              <dbl>     <dbl>     <dbl>   <dbl>
