A method named for Welch and this letter approximates solutions to the Behrens–Fisher problem. A dimension reduction method often used to visualize genomic data is named ”[this letter]-SNE (20[1])(“snee”).” The coefficient of determination equals the complement of the ratio of the residual sum of squares to a quantity denoted (0[1])”[this letter] SS.” (0[1])A (*) distribution named for this (0[1])letter converges (0[1])to a standard normal distribution as degrees (0[1])of freedom tend (10[1]0[1])towards (10[4]0[1])infinity. (10[1]0[2])When (10[1])sample size is (10[1])small or variance is unknown, a statistic denoted (0[1])with this letter is used (0[1])instead (0[1])of the z-score in a namesake test. (10[3]0[1])For (10[1])10 points, (0[1])give this letter that names (10[1])“Student’s” distribution, which is like the normal distribution, but with heavier tails. (10[5])■END■ (10[9]0[7])
