Structural equation modeling (SEM) is a modern form of statistical analysis used to study relationships between variables in complex data sets. This method allows researchers to create a model that describes the influence of different variables on the behavior of an individual or group. SEM can be used to improve research results by testing hypotheses about relationships between variables, considering multiple variables simultaneously.

The least squares method is a procedure for fitting data to a mathematical function. It is commonly used in statistical analysis to estimate the parameters of a given function from a set of observed data points. The procedure consists of minimizing the deviation between the observed values and the predicted values by adjusting the parameters of the function.

Analysis of variance is a statistical data analysis technique used to study the differences between two or more groups. It is often used to find out how much influence each variable has on a particular measured variable. Analysis of variance can also be used to evaluate the strength of the relationship between two or more variables.

The standard error is a mathematical quantity that describes the variance of a measured value of a sample. The standard error is often used to determine the accuracy of a sample. It indicates how much the measured values in a given sample deviate from the average value.

Markov chains are a mathematical approach used to model random behavior. They are often used to simulate random processes based not only on the current situation, but also on previous events. They use probability distributions to predict how likely certain events are. This technique is commonly used in fields such as natural sciences, finance, artificial intelligence and data analysis.
