BLAND_ALTMANN shows the Bland-Altman plot of two columns of measurements and computes several summary results. bland_altman(m1, m2 [,group]) bland_altman(data [, group]) R = bland_altman(...) m1,m2 are two colums with the same number of elements containing the measurements. m1,m2 can be also combined in a single two column data matrix. group [optional] indicates which measurements belong to the same group This is useful to account for repeated measurements.
