Likelihood Ratio Statistics for 2 x 2 Tables
Choi et al. PLOS One 2015
Warning: The input values for number of successes must be between 1 and the sample size for each treatment group.
The number of success for treatment 1
The number of success for treatment 2
The sample size for treatment 1
The sample size for treatment 2
This calculator provides p-values based on the profile and conditional likelihood ratio (LR) statistics for 2 x 2 tables. The function also provides the profile and conditional likelihood support intervals (k=6.8) corresponding to a 95% confidence interval based on a normal approximation.
For comparison purpose, p-values from Pearson's Chi-squared test, Fisher's exact test and Pearson's Chi-squared test with continuity correction are also provided.
