WebThe T-Distribution is a measure of probability (p-value). It is used to find the statistical significance when the sample size is small, i.e., less than 30, with an obscure standard deviation. The mean of a T-Distribution is evaluated as zero, and the variance is derived as v/ (v-2), where v is the degree of freedom. WebIn probability and statistics, Student's t-distribution (or simply the t-distribution) is any member of a family of continuous probability distributions that arise when estimating the mean of a normally …
WebSep 1, 2024 · I'm struggling to show that the moment generating function for t distribution does not exist. So far I tried to show the moment generating function diverges from its integration but the computation is not so easy (I'm stuck at partial integration). If there is any easier way to show that there is no MGF without any computation or any hints for ... WebThe t -distribution seems to be quite similar to the standard normal distribution. Using the formula given above for the p.d.f. of T, we can plot the density curve of various t random variables, say when r = 1, r = 4, …
