WebDec 14, 2024 · We are now ready to use the mvrnorm function in R to simulate some number n of sampled organisms with these three measurements. We use the mvrnorm arguments mu and Sigma to specify the vector of means and covariance matrix, respectively. Hide. sim_data <- mvrnorm (n = 40, mu = mns, Sigma = cv_mat); WebThe standard confidence intervals for the difference of means are computed that can be found in many textbooks, e.g. Chapter 4 in Altman et al. (2000). The method "classical" assumes equal variances whereas methods "welch" and "hsu" allow for unequal variances. The latter two methods use different formulas for computing the degrees of freedom ...
