We consider the problem of testing significance of predictors in multivariate nonparametric quantile regression. A stochastic process is proposed, which is based on a comparison of the responses with a nonparametric quantile regression estimate under the null hypothesis. It is demonstrated that under the...

Unless otherwise stated, the common default significance level is α=0.05. For our conformity example, for the sake of using various significance levels, we will use the significance level of α=0.01. View chapterExplore book Simple linear regression Stephen C. Loftus, in Basic Statistics with R...
That's where you'll need to weigh the statistical significance against the practical relevance for your business objectives. For more information on how to approach this type of analysis, visitour regression analysis guidewhich helps you understand and predict outcomes. ...
The technique of geographically weighted regression (GWR) is used to model spatial 'drift' in linear model coefficients. In this paper we extend the ideas of GWR in a number of ways. First, we introduce a set of analytically derived significance tests allowing a null hypothesis of no spatial...
How to choose the level of statistical significance for test of equaility of seemingly unrelated regression coefficients? It is possible to compare effects from models estimated as seemingly unrelated [1] [2] [3]. For instance, DVs may be related or IVs may be related. In any event, analyst...
What is a significance level? Now, the significance level (α) is a value that you set in advance as the threshold for statistical significance. In simple terms, it’s the probability of rejecting the null hypothesis when it’s true. For example, a significance level of 0.05% indicates a...
In a Cox regression analysis identifying predictors for PSA relapse-free survival, only preradiotherapy PSA was significantly associated with biochemical control; IG-IMRT was not a statistically significant indicator.
