The Probit Model is a type of regression used in statistics to model binary outcome variables, where the probability of a particular outcome is determined by a cumulative normal distribution function. It is particularly useful when the underlying latent variables are assumed to follow a normal distribution, offering an alternative to the logistic regression model with its own unique properties and interpretations.

Regression is a statistical method used to model and analyze the relationships between a dependent variable and one or more independent variables. It is widely used for prediction and forecasting, allowing for the understanding of how changes in predictors influence the outcome variable.

Latent variables are unobserved variables that are inferred from observed data, often used to explain patterns or structures that are not directly measurable. They are crucial in statistical models such as factor analysis, structural equation modeling, and latent class analysis, providing a way to model complex phenomena by capturing hidden influences or traits.

The normal distribution, also known as the Gaussian distribution, is a continuous probability distribution characterized by its symmetrical bell-shaped curve, where the mean, median, and mode are all equal. It is fundamental in statistics because many natural phenomena and measurement errors are approximately normally distributed, making it a cornerstone for statistical inference and hypothesis testing.
