## Question:

I have a dataset to do the logistic regression of the dependent variable childbirth which is binary qualitative.

With the command below I obtain the multivariate logistic model in the R program:

```
GLM.1 <- glm(parto ~ trabalho + financiamento + consulta, family=binomial(logit), data=Dataset)
```

The independent variables of this model are also binary qualitative.

I would like to know which R command should I use to get the Hosmer-Lemeshow test to check if this model fits.

If it is necessary to use a specific R package for this, I would like to know what this package would be and which function to use.

## Answer:

With a quick search on Stack Overflow in English and with `R`

's own `RSiteSearch`

command I found 2 functions for such a test. `hoslem.test`

from the `ResourceSelection`

package and `logitgof`

from the `generalhoslem`

package
