Multiepisode models : Multiepisode models are a type of reinforcement learning algorithm that can learn from multiple episodes of an environment. This means that the model can learn from a series of interactions with the environment, rather than just a single episode. This is useful in many situations because it allows the model to learn […]

Multidimensional scaling (MDS) : Multidimensional scaling (MDS) is a technique used to visualize the underlying similarities and dissimilarities between a set of objects or items. It does this by representing the objects in a low-dimensional space (typically two or three dimensions) while preserving the distances between the objects as much as possible. In other words, […]

Multicollinearity : Multicollinearity refers to a situation in which two or more predictor variables in a regression model are highly correlated with each other. This can lead to unstable and inaccurate coefficient estimates, as well as problems with model interpretation. One example of multicollinearity is when using multiple indicators of income in a regression model, […]

Multicentre study : A multicenter study is a type of clinical research study that is conducted at multiple locations, or centers. This type of study is typically used to evaluate the safety and effectiveness of a medical treatment, diagnostic test, or other medical intervention. Multicenter studies are often large and complex, involving many different research […]

Mplus : Mplus is a statistical software program that is commonly used for latent variable modeling, which includes a range of statistical techniques such as structural equation modeling (SEM), growth curve modeling, and multilevel modeling. Mplus allows users to fit a wide range of complex models to their data, and it offers several advantages over […]

Moving-average : Moving average is a technique used in technical analysis to smooth out short-term fluctuations in a data series and to highlight the underlying trend. It is calculated by taking the average of a certain number of past data points, typically over a specified period of time. For example, let’s say we are analyzing […]

Mosaic displays : Mosaic displays are computer displays that are made up of a grid of individual pixels, each of which can be a different color. This allows for the creation of highly detailed and complex images on the screen. One example of a mosaic display is a modern smartphone or tablet screen. These displays […]

Morbidity : Morbidity refers to the state of being unhealthy or having a disease or medical condition. It is typically used to describe the prevalence or incidence of a specific illness or condition within a population. One example of morbidity is the widespread prevalence of obesity in the United States. According to the Centers for […]

Mood’s test : Mood’s test, also known as the chi-squared test for independence, is a statistical test used to determine if there is a significant association between two categorical variables. It is commonly used in research to examine the relationship between a dependent variable and one or more independent variables. One example of using Mood’s […]

Monty Hall problem : The Monty Hall problem is a probability puzzle named after the host of the game show “Let’s Make a Deal.” The problem involves a contestant who is given the choice of three doors: behind one door is a prize, while behind the other two are goats. After the contestant picks a […]
