The paper is devoted to a new randomization method that yields unbiased adjustments of p-values for linear regression model predictors by incorporating the number of potential explanatory variables, their variancecovariance matrix and its uncertainty, based on the number of observations. This adjustment ...
F-statistic: 1.16e+03 on 1 and 270 DF, p-value: <2e-16 Decide whether there is a significant relationship between the variables in the linear regression model of the data setfaithfulat .05 significance level. NULL hypothesis: no relationship between x and y, so the slope is zero. 假设...
We could have found the p-value using a Z-test instead, in the event that we know the population standard deviation. P-values show up in many places, including, as further examples, in linear regression, where p-values assess the significance of model coefficients, or in ANOVA testing. Ta...

A test to compare two nested regression models. The test statistic follows the F-distribution with (k2 - k1, n - k2)-degrees of freedom, where k1 and k2 are the numbers of variables in the smaller and bigger models, respectively, and n is the sample size. You may notice that the F...
