Digital terrestrial television services using the DVB-T standard will be launched later this year in the UK, followed by Sweden and perhaps other countries soon afterwards. Reception of these services will make use of domestic set-top boxes and integrated receivers using DVB-T demodulator ICs (integrated circuits). The first of these ICs are now becoming available, and it is important that thei...

It is shown that the global power function of any nonparametric test is at on balls of alternatives except for alternatives coming from a nite dimensional sub-space. The present benchmark is here the upper one-sided (or two-sided) envelope power function. It turns out that also the level points are far away from the corresponding Neyman Pearson test level points except for a nite number of orth...

Panel estimators can provide consistent measures of a long-run average parameter even if the individual regressions are spurious. However, the t-test on this parameter is fraught with problems because the limit distribution of the test statistic is non-standard and rather complicated, particularly in panels with mixed (non-)stationary errors. A sieve bootstrap framework is suggested to approxim...

Normatively, a statistical pairwise comparison is a function of the mean, standard deviation (SD), and sample size of the data. In our experiment, 203 undergraduates compared product pairs and judged their confidence thatone product was better than the other. We experimentally manipulated (within subjects) theaverage productratings, the number of raters (sample size), and the SD of the ratings....

In this paper we discuss nonparametric goodness of t theory for alternatives , which, in practical terms, manifest themselves not as a \smooth" and \small" deviation \everywhere", but as still not big systematic \stains" or highly oscillating patterns as compared to the regular null hypothesis.
