Ease to calculate the sample size with n4Studies Plus.
n4Studies Plus makes it easy to calculate the sample size and the power of a study in various study designs. It comes with ABSOLUTELY NO WARRANTY. However, It can be helped to learn and find the ways to calculate the sample size and power of the study in minutes.
Key features:
• Calculate the sample size for simple and multiple linear regression, logistic regression
• Calculate the sample size for survival analysis e.g. compare 2 survival curves, compare for equality between 2 hazard rates etc.
• Calculate the sample size for diagnostic study, cross-over study
• Calculate the sample size for estimating an infinite population mean, finite population mean, infinite population proportion and finite population proportion
• Calculate the sample size for comparing two population means and two population proportions
• Calculate the sample size for the Case-Control for study, Matched Case-Control study, Cohort study, Randomized Controlled Trial, Non-inferiority trial and Equivalence trial
• Calculate the power of a study for comparing two population means and two population proportions
• Calculate the power of a study for the Case-Control for study, Matched Case-Control study, Cohort study, Randomized Controlled Trial, Non-inferiority trial and Equivalence trial
• Sample size and power calculations for measures of Agreement (both Kappa statistic and Intraclass correlation coefficients)
• You can send a output via Email to your colleagues
