Recently, there has been increased interest in issues related to functional linear regression models with points of impact. While the estimation of model parameters with a scalar response has been considered in past studies, there has been no attention on the hypothesis testing for these impact ...

The estimator is an easily computable function of the observed inputs and outputs . These two properties are used to derive the asymptotic distribution of the test statistics used in hypothesis testing. Test of a restriction on a single coefficient (z test)In a z test the null hypothesis is ...
Both hypothesis testing with ANOVA and linear regression were used for quantitative data analysis. The main finding is that the perceived quality of the lighting environment correlates with perceptions about the potential for restoration, thus... H Nikunen - 《Aalto University Publication》 被引量: ...
In this chapter we consider (linear) hypothesis testing in the linear model under the normality assumption. We establish the properties of the t-test and the F-test and provide an interpretation of the F test in terms of goodness of fit. We also define the trinity of likelihood tests for ...

Linear mixed modelNested error regression modelConsider the problem of testing the linear hypothesis on regression coefficients in the nested error regression model. The standard F-test statistic based on the ordinary least squares (OLS) estimator has the serious shortcoming that its type I error ...

In this note, we analyze the sampling performance of the two-stage test that tests the linear hypothesis on regression coefficients after a pre-test for disturbance variance. It is shown that the two-stage test has a serious upward bias in size when the degrees of freedom is small, but it...
