The following is the same fit using the tweedie family:
```{r}
-tweedieGLM1 <- spark.glm(carsDF, mpg ~ wt + hp, family =
SparkR:::tweedie(0.0))
+tweedieGLM1 <- spark.glm(carsDF, mpg ~ wt + hp, family = "tweedie",
variancePower = 0.0)
summary(tweedieGLM1)
```
We can try other distributions in the tweedie family, for example, a
compound Poisson distribution with a log link:
```{r}
-tweedieGLM2 <- spark.glm(carsDF, mpg ~ wt + hp, family =
SparkR:::tweedie(1.2, 0.0))
+tweedieGLM2 <- spark.glm(carsDF, mpg ~ wt + hp, family = "tweedie",
+ variancePower = 1.2, linkPower = 0.0)
summary(tweedieGLM2)

let's add an example with `statmod` too? either here or in roxygen2 API doc
(later might be a better place?)
