Document Summary
15, pg 205: goodness of fit test: this test is for assessing if a particular discrete model is a good fitting model for a discrete characteristic, based on a random sample from the population, test of homogeneity: this test is for assessing if two or more populations are homogeneous (alike) with respect to the distribution of some discrete (categorical) variable, test of independence: this test helps us to assess if two discrete (categorical) variables are independent for a population, or if there is an association between the two variables. You also have the test() function using r to find the exact p-value. :0h a specified discrete probability distribution for x. We have 1 random sample of size n . We measure 1 discrete response x that has k possible outcomes. :ah not all probabilities specified in the null hypothesis are correct. p. E = np i where expected degrees of freedom, where k is.
