Analyse-it® Standard Edition
Describe, visualise, and test if two qualitative or quantitative measures agree
or disagree.
Analyse-it provides the most complete implementation of Bland-Altman plots available,
including the latest recommendations from Bland and Altman. Kappa and Weighted Kappa
are included for examining inter-rater (qualitative) agreement.
- Describe and test agreement
Bias and limits of agreement (with confidence intervals) are shown, with a hypothesis
test that bias is zero. Differences can be transformed to ratios or relative percentage
if variance is non-constant over the measurement range.
- Visualise agreement with difference and scatter plots
Visualise the agreement with Bland-Altman difference plot (also known as Tukey mean-difference
plot) showing bias and limits of agreement, a scatter plot with line of equality,
or a histogram of differences.
- Visualise repeatability
- Describe and test agreement between qualitative variables
Calculates Kappa & Weighted Kappa (supports linear and quadratic weightings) with
confidence intervals. Tests the hypothesis of no agreement.
For a more extensive range of difference plots for analytical method comparision
in the laboratory, see Analyse-it
