The Mplus program can do more than just help you complete your work. It is a collection of advanced statistical modeling techniques that are used for both empirical data analysis and creating mathematical models. The ability to run these models on large datasets can be sometimes be limited, but Mplus has found a way around this difficulty by making it possible to run the programs using an online connection. This innovative new feature is now available, helping make the powerful capabilities of the Mplus program even more accessible. This article highlights some of these newest features in addition to providing background information on how they are put together. We also highlight features most beneficial for educators and students, as well as highlighting their strengths over other similar programs. Data can be entered in to an Mplus program in a number of ways, but the most common is to use one of the many import or export tools that Mplus has available. The data must be trimmed, if it is too long, and data can be added or removed at any point. The use of these tools will quickly give the user insight into how the data was entered. From here, users can either write their own code or use pre-existing code written by other Mplus users. The former option allows users to make changes without having to redeploy their model while the latter option allows users to take advantage of existing code written by others. The program uses MATLAB syntax for code input and output. This feature allows the modeler to use external optimization tools and interface with other statistical programs. Mplus has many options for external input and output allowing users to enter their data in multiple ways. The modeler can choose from allowing the user to input the data into Excel sheets or save it as either a binary file or text file. These features help make it much easier for others using different operating systems to run the program, especially when using missing values, which are handled differently in each system. Mplus provides an option called "Reliability Analysis," which enables users to estimate the reliabilities of observed variables, standardized observed variables, observed scores, latent variables, observed variable means, observed variable variances and covariances between observed variables. This feature is useful when there are missing values in the data. The program has many statistical techniques built into it, allowing users to model variables with less bias, more efficient fitting and greater accuracy across all of the parameters in the model. There are many different estimation techniques available to fit your data, including Maximum Likelihood Estimation (MLE), Maximum A Posteriori (MAP) Estimation and Ridge Regression. There are several algorithms for each technique that can be changed to achieve the most accurate results for any given situation. Once a model has been entered into Mplus, it builds a dynamic model structure with multiple input tab boxes where users can choose their specific statistical techniques or create their own. Through this process, Mplus generates a set of equations that can be analyzed and solved to obtain confidence intervals, plots and other relevant information. Once the calculations are completed, the program generates the output as a file for further analysis. Mplus can also be used as a graphing/visualization tool for the results of your model. There are multiple options for adding graphs to your outputs, which includes panel graphics and tables. Regardless of what method is chosen, users will be able to easily identify specific changes and/or reliabilities in the data through these diagrams. eccc085e13
