How does the chi square goodness of fit test work?

The chi-square goodness-of-fit test determines if a data sample comes from a specified probability distribution, with parameters estimated from the data. where Oi are the observed counts and Ei are the expected counts based on the hypothesized distribution.

Which is the best value for the goodness of fit?

It is also called the summed square of residuals and is usually labeled as SSE. A value closer to 0 indicates that the model has a smaller random error component, and that the fit will be more useful for prediction. This statistic measures how successful the fit is in explaining the variation of the data.
