WebFor example, if all your cells have expected higher than 1 and about 80% are above 5, you're probably safe just treating it as chi-square (in that the p-values will still be roughly correct in instances you'll care to have good accuracy in). If expecteds are close to equal you can go lower.

Hosmer and Lemeshow’s goodness of fit test was used to check the goodness of fit of the model. WebA p-value less than or equal to 0.05 does not indicate that the groups are definitely different. Instead, it suggests that the null hypothesis is probably not true and provides guidance to reject the null hypothesis and accept the alternative hypothesis, i.e. that the groups probably differ.

WebApr 11, 2024 · The p-value is 0.002, which tells us that the intercept term is statistically different than zero. In practice, we don’t usually care about the p-value for the intercept term. Even if the p-value isn’t less than some significance level (e.g. 0.05), we would still keep the intercept term in the model. WebAnd if that probability is lower than our significance level, if that probability is less than 5/100, if it's less than 5%, then we reject the null hypothesis and say that we have …
