the null hypothesis

the null hypothesis hypothesis testingtell the step 一道统计学题,A test of a null hypothesis gives a test statistic z=-1.6what is p-value if the alternative is Ha:u不等于u0? 英语翻译In this paper,we consider the statistical problem of testing the null hypothesis that a stochastic process is stationary against the alternative that it is integrated of order 1 (i.e.,it is nonstationary but becomes stationary after first 英语翻译Tests the null hypothesis that the error variance of the dependent variable is equal across groups.a.Design:Intercept + 被试性别 + 对象性别 + 被试性别 * 对象性别 英语翻译求翻译：we use Wilcoxon's signed rank test against the null hypothesis that a set of values is symmetrically distributed with mean zero在论文里看到,求翻译,求大牛 统计学中关于第一类错误和第二类错误当null hypothesis为假时,哪一类错误is avoided呢?求指教 Define the term hypothesis and identify three ways in which a hypothesis can be tested. hypothesis是什么意思? 什么是hypothesis hypothesis是什么意思 Find a basis for the null space of the matrix what is contrastive analysis hypothesis?and what are the strengths and weaknesses?what is interlanguage? the rival hypothesis什么意思最好把详细点的中文解释说下呵呵~~ 请问格兰杰因果关系如何检验,谢谢.Null Hypothesis: Obs F-Statistic Probability LNW does not Granger Cause LNCONS 9 1.92071 0.26021 LNCONS does not Granger Cause LNW 0.46121 0.66033 LNY does not Granger Cause LNCO eviews5.0下wald检验的结果怎么看啊Wald Test:Equation:EQ01 Test Statistic Value df ProbabilityF-statistic 0.101370 (1,28) 0.7526Chi-square 0.101370 1 0.7502_______________________________________________ Null Hypothesis Summary:Normalized Res Model Fit StatisticsInterceptIntercept andCriterion Only CovariatesAIC 144.206 59.848SC 147.230 147.540-2 Log L 142.206 1.848Testing Global Null Hypothesis:BETA=0Test Chi-Square DF Pr > ChiSqLikelihood Ratio 140.3582 28 the specified call count is not a number:null
