Reliability study designer
File name : 'Shoukri.m'. This file can be used
for calculating the required number of subjects
at a desired kappa value for reliability
assessment.
Five input values : 'alfa', 'omega', 'pi', 'rho' and 'kappa'
Three output value : 'k', 'n' and 'N'
alfa : significance level (value between 0 and 1)
omega : desired interval of kappa (value between 0 and 1)
pi : probability of positive rating (value between 0 and 1)
rho : within-subject interclass correlation
kappa : desired coefficient of agreement (value between 0 and 1)
k : number of subjects (value larger than 1)
n : number of replication (value equal to or larger than 1)
N : number of allocations (value larger than 1)
Figure : plot of the number of subjects versus the number of replications
Input syntax : Shoukri(alfa,omega,pi,kappa)
NOTE: No default values are set
