WebMar 15, 2024 · Abstract. We propose a two-sample test for the mean functions of functional data when the number of bases is much lager than the sample size. The novel test is based on U-statistics which avoids estimating the covariance operator accurately under the high dimensional situation. We further prove the asymptotic normality of our test statistic ... WebTo calculate the sample covariance, the formula is as follows: COVARIANCE.S (array1,array2) In this formula, array1 is the range of cells of the first data set. In our case, this would be the Marks starting from cell B2 to cell B15. Likewise, array2 is the range of cells of the second data set.
