The comment (copy-pasted from the example script) is also a bit misleading because tdist = TRUE is not the same thing as the Knapp-Hartung adjustment. ... data=df, rho=0.6) > > Once you've got the V matrix, you feed it into the V argument of rma.mv() > as follows: ... WebThis gives result that Pr(X > 1.9) = 0.0449. So Pr(X <= 1.9) = 1 - 0.0449 = 0.9551. Much simpler is to directly type in the cell = 1 - TDIST(1.9, 9, 2) and hit . 2. Find the value x* such that Pr(X <= x*) = 0.9 when x is t-distributed with 9 degrees of freedom. This is the same value as that for which Pr( X >= x*) = 0.2. ... gold tipped lipstick
