taking a decision based on it, and then discover that by adoption of a slightly variant one the decision would have been drastically different (Paruolo et al.,2013). Additionally, it seems plausible that some choices in the models of measurement make the final indicator easier to be ‘gamed...
Calculating confidence intervals in R is a handy trick to have in your toolbox of statistical operations. A confidence interval essentially allows you to estimate about where a true probability is based on sample probabilities at a given confidence level compared to your null hypothesis. The confide...
In this tutorial, I will show you how to perform a Spearman rank correlation test in R. What is a Spearman correlation test? A Spearman’s rank correlation test is a non-parametric, statistical test to determine the monotonic association between two variables. Example data For this tutorial, ...
It is possible, but difficult, to compute these values and we are considering do so in the future (to allow computation at more significance levels). These references explain how: Calculation of critical values for Dunnett and Tamhane's step-up multiple test procedure ...
In thefield of statistics, data are vital. Data are the information that you collect to learn, draw conclusions, and test hypotheses. After all, statistics is the science of learning from data. However, there are different types of variables, and they record various kinds of information. Cruci...
How to Use VIFs: Compute VIFs for Each Predictor Variable: Statistical software can calculate VIF values for all predictors in your regression model. Assess the VIF Values: VIF = 1: Indicates no correlation with other predictors. VIF between 1 and 5: ...
