How does the t distribution relate to the analysis of political science data?

Sep 21, 2024 ... I am looking for the multi-variate t distribution, which is commonly used for Ba...yesian linear regression. We estimate the parameters of the GARCH model for the conditional variance, using the pseudo-maximum-likelihood (PML) procedure advocated by Bollerslev and ... A Student's t table gives t-scores given the degrees of freedom and the right-tailed probability. The table is very limited. [[A physical bell-curve-shaped object labeled "Student's t distribution" is resting on a table. A figure is working with it and a piece of paper.]] Figure ...

Student t-distributions are very close to the standard normal distribution, and become closer as the number of degrees of freedom increases. Student's T distribution.
