This example shows how to compare two competing, conditional variance models using a likelihood ratio test. Step 1. Load the data and specify a GARCH model. Load the Deutschmark/British pound foreign exchange rate data included with the toolbox, and convert it to returns. Specify a GARCH(1,...
This example illustrates how the likelihood ratio statistic can be used. Let , that is, the parameter space is the set of all -dimensional real vectors. Denote the three entries of the true parameter by , and . The restrictions to be tested areso that is a function defined by ...
Example 9.2 Likelihood Ratio Test for the Order of a Markov Chain To illustrate the application of Equations 9.13, consider a likelihood ratio test of first-order dependence of the binary time series in Table 9.1, versus the null hypothesis of zero serial correlation. The test involves computation...
Likelihood Ratio Test The Likelihood Ratio(LR) test is based on the concept of F test in a linear model. The F test measures the increase in the sum of squared residuals when variables are dropped from the model. Let’s have a non-statistical example. Suppose you are one of 11 soccer ...
For example confidence intervals of estimated parameters rely on the statistical properties of the likelihood-ratio test. However, it is often overlooked that these intervals sizes rely on assumptions on the amounts of data, which are regularly violated in typical appli...
A classical example is testing for a disease. The subject tests positive for the disease, under a test that has a true positive rate of 60% (only 60% of the afflicted trigger a positive response for the disease) and a false positive rate of 1% (1% of healthy people trigger a positive...
The procedure is illustrated by an example. A Monte Carlo experiment also shows how good the approximation is for a specific case. Key words: eovariance structure analysis, um likelihood estimation, likelihood ratio test, power of the test, local alternatives, noncentral Chi-square, noncentrality...
