We already know how to test this hypothesis using chi-squared goodness-of-ﬁt test. If dis tribution P0 is continuous we had to group the data and consider a weaker discretized null hypothesis. We will now consider a diﬀerent test for H0 based on a very diﬀerent idea that avoids this discretization. 1 1 0.2 all data normal fit 0.2 0.1 0.1 0 0 96 96.5 97 97.5 98 98.5 99 99.5 100 100.5 96

An attractive feature of the chi-squared goodness-of-fit test is that it can be applied to any univariate distribution for which you can calculate the cumulative distribution function. The null hypothesis is a statement that is assumed true.
The goodness-of-fit test is almost always right-tailed. If the observed values and the corresponding expected values are not close to each other, then the test statistic can get very large and will be way out in the right tail of the chi-square curve.

goodness-of- t test based on the distribution of the variable exp( Nf(x i )V(x i )), where f(x i ) is the ex- pected density at the observed point x i , V(x i ) is the
The test for this similarity using the chi-square variable is called a “goodness-of-fit” test. Consider a sample of N observations from a random variable X with observed PDF p 0 ( X ). Let the N observations be grouped into K intervals (or categories) called class intervals, whose graphical distribution forms a frequency histogram ( Bendat and Piersol, 1986 ).

This book provides the reader with a unified analysis of the traditional goodness-of-fit tests, describing their behavior and relative merits as well as introducing some new test statistics. The power-divergence family of statistics (Cressie and Read, 1984) is used to link the traditional test statistics through a single real-valued parameter, and provides a way to consolidate and extend the

A goodness-of-fit test, in general, refers to measuring how well do the observed data correspond to the fitted (assumed) model. We will use this concept throughout the course as a way of checking the model fit. Like in a linear regression, in essence, the goodness-of-fit test compares the observed values to the expected (fitted or predicted) values. A goodness-of-fit statistic tests the
