linear model

A linear model is a mathematical tool used to predict or understand the relationship between different factors. It assumes that the outcome can be described as a straight-line combination of input variables. For example, if you're estimating house prices, factors like size, location, and age can each be multiplied by a number (coefficient) and added together to give an estimated price. This approach is straightforward, interpretable, and works well when relationships between variables are roughly linear, helping us understand how changing one factor might impact the result.
