srktie_m {EQUIVNONINF} | R Documentation |
Analogue of the function srktie_d tailored for settings where the distribution of the within-subject differences is concentrated on a finite lattice. For details see Wellek S (2010) Testing statistical hypotheses of equivalence and noninferiority. Second edition, pp.112-3.
srktie_m(n,alpha,eps1,eps2,w,d)
n |
sample size |
alpha |
significance level |
eps1 |
absolute value of the left-hand limit of the hypothetical equivalence range for q_+/(1-q_0) - 1/2 |
eps2 |
right-hand limit of the hypothetical equivalence range for q_+/(1-q_0) - 1/2 |

Notation: q_+ and q_0 stands for the functional defined by q_+ = P[D_i+D_j>0] and q_0 = P[D_i+D_j=0], respectively, with D_i and D_j as the intraindividual differences observed in two individuals independently selected from the underlying bivariate population.
