How do you interpret the p-values associated with regression coefficients?

Critical Values for Student's t-Distribution. Upper Tail Probability: Pr(T >t) df. 0.2. 0.1. 0.05. 0.04. 0.03. 0.025. 0.02. 0.01. 0.005. 0.0005. 1. 1.376. 3.078. Student's t-distribution ... Student's t-distribution is a probability distribution which was developed by William Sealy Gosset in 1908. Student is the pseudonym ... Mar 18, 2022 ... Implementation in R: Here is some code to implement this MLE analysis in R in a simple way, without analytic computation of the gradient or ... The t distribution provides a good way to perform one sample tests on the mean when the population variance is not known provided the population is normal. Upper critical values of Student's t distribution with degrees of freedom. Probability of exceeding the critical value. 0.10 0.05 0.025 0.01 0.005 0.001. 1 ... Dec 13, 2023 ... Up until the mid-1970s, some statisticians used the normal distribution approximation for large sample sizes and used the Student's t- ... If Y has a Student's t distribution with ν degrees of freedom, then X = 1 2 + 1 2 Y ν + Y 2 has beta distribution with the shape parameters a = ν/2 and b = ν/2. Oct 12, 2023 ... We address the problem of computing a consistency factor for the MCD estimator in a heavy-tail scenario, when uncontaminated data come from a multivariate ... Student's t-distribution is defined as the distribution of the random variable t which is - very loosely - the "best" that we can do not knowing the true ... Student t-distributions are very close to the standard normal distribution, and become closer as the number of degrees of freedom increases.
