What are the assumptions of the two-sample independent t-test?

In 1912 Gosset communicated with a young statistician, Ronald Fisher, who would have an enormous impact on the acceptance of Student's distribution in day-to- ... May 11, 2012 ... The t-distribution is very closely related to the standard normal distribution and, like the normal, is a symmetric bell-shaped distribution. TDist: The Student t Distribution. Description. Density, distribution function, quantile function and random generation for the t distribution with df degrees ... tcdf( computes the Student t distribution probability between lowerbound and upperbound for the specified df (degrees of freedom), which must be > 0. Overview. The Student's t distribution is a one-parameter family of curves. This distribution is typically used to test a hypothesis regarding the population ... qt(p, d)—Returns the inverse cumulative probability distribution for probability p. • rt(m, d)—Returns a vector of m random numbers having the Student's t- ... We suggest a log-normal prior as a viable prior option. We show that the Bayesian estimator based on a log-normal prior compares favorably to other Bayesian ...
