We are excited to introduce you to the new features in Stata 16. Below, we list highlights of the release. In what follows, we tell you a little more about the first 13 of them. We introduce each feature using words that you might also use as you introduce them to existing and potential Stata users. The majority of these features will be exciting to researchers in all disciplines. Where appropriate, we will highlight which disciplines will be most interested or provide advice about how different groups of users will relate to the feature. We
Sample-size analysis for confidence intervals in Stata 16 The new ciwidth command performs Precision and Sample Size (PrSS) analysis, which is sample-size analysis for confidence intervals (CIs). This method is used when you are planning a study and you want to optimally allocate resources when CIs are to be used for inference. Said differently, you use this method when you want to estimate the sample size required to achieve the desired precision of a CI in a planned study. ciwidth produces sample sizes, precision, and more that are required for the • CI for one mean • CI for one variance • CI for two independent means • CI for two paired means The control panel interface lets you select the analysis type and input assumptions to obtain desired results. ciwidth allows results to be displayed in customizable tables and graphs. ciwidth also provides facilities for you to add your own methods.
