Handbook of Statistical Distributions with Applications, Second Edition provides quick access to common and specialized probability distributions for modeling practical problems and performing statistical calculations. The development of the kappa and Lin’s concordance calculator tools was funded by NZ Ministry of Health, the Foundation for Research, Science and Technology (FRST), and Environmental Diagnostics Ltd.Easy-to-Use Reference and Software for Statistical Modeling and Testing Water and Wastes in New Zealand (November): 43–45, 60. Monitoring the microbiological quality of drinking-waters. Using Statistical Methods for Water Quality Management: Issues, Problems and Solutions. A note on the concordance correlation coefficient. A concordance correlation coefficient to evaluate reproducibility. The measurement of observer agreement for categorical data. Statistical methods for rates and proportions, 2nd ed., Wiley, p. Educational and Psychological Measurement 20(1): 37–46. A coefficient of agreement for nominal scales. These procedures guard against the risk of claiming good agreement when that has happened merely by "good luck". Statistical testing procedures for Cohen’s kappa and for Lin’s concordance correlation coefficient are included in the calculator. Values of ☑ denote perfect concordance and discordance a value of zero denotes its complete absence. It calculates the value of Lin’s concordance correlation coefficient. Lin’s concordance calculator is used to assess the degree of agreement between two continuous variables, such as chemical or microbiological concentrations. A value of κ = 1 denotes perfect concordance, k = 0 denotes agreement by chance alone. It calculates the value of Cohen’s "kappa" (κ). Such variables may have one of only two "values", e.g., presence or absence. The kappa calculator is used to assess the degree of agreement between two dichotomous variables. You can download pdf files explaining the main features of all these tests. The "detection probability" is usually the more familiar "statistical power", except for the case of testing the inequivalence hypothesis (postulating that a difference lies beyond an "equivalence interval") in that case it is the test’s "operating characteristic". For equivalence tests only the detection probability can be calculated (further options will be added at a later date) its results are followed by an instructive graphical comparison of the effect of sample size on the detection probabilities for tests of the inequivalence hypothesis, the equivalence hypothesis, and the point-null hypothesis. You specify any three of these and it calculates the remaining one. For the first two types of hypothesis you can specify one of: the sample size, the significance level, the detectable effect size, and its detection probability. You can use either one or two groups of samples-all assuming random sampling from a normal distribution. The Detection calculator is used to examine and calculate various properties of tests of three types of hypotheses: one-sided, point-null and equivalence.
