goodness of fit test example

As far as I know the Hosmer-Lemeshow goodness of fit test is overall used to assess goodness of fit in logistic regression with individual binary data. The result h is 1 if the test rejects the null hypothesis at the 5 significance level and 0 otherwise.

H chi2gofx returns a test decision for the null hypothesis that the data in vector x comes from a normal distribution with a mean and variance estimated from x using the chi-square goodness-of-fit testThe alternative hypothesis is that the data does not come from such a distribution.

. Goodness-of-fit tests are often used in business decision making. As with any topic in mathematics or statistics it can be helpful to work through an example in order to understand what is happening through an example of the chi-square goodness of fit test. This test is a type of the more general chi-square test.

Used in statistics and statistical modelling to compare an anticipated frequency to an actual frequency. I understand that in general grouped binary data implies that some or a few at least not an infinite number of groups of individuals share the same. The chi-square goodness of fit test is a useful to compare a theoretical model to observed data.

Would it be sensible to use it also for grouped binary data.
