Linear regression continuous variable
Did you know?
NettetLinear regression analysis rests on the assumption that the dependent variable is continuous and that the distribution of the dependent variable (Y) at each value of the independent variable (X) is approximately normally distributed. Note, however, that the independent variable can be continuous (e.g., BMI) or can be dichotomous (see below). NettetThe most popular form of regression is linear regression, which is used to predict the value of one numeric (continuous) response variable based on one or more predictor variables (continuous or categorical). Most people think the name “linear regression” comes from a straight line relationship between the variables.

Nettet3. aug. 2024 · 4. Usually, with a continuous dependent variable, we can apply linear regression and then predict values based on new data. For instance, defaults on loans: let's say we know an individual will default on his loan, and we want to estimate how long it takes him to default (1 year, 2 years, 3 years... after he took the loan).

NettetRegression analysis is used when you want to predict a continuous dependent variable from a number of independent variables. If the dependent variable is dichotomous, then logistic regression should be used. (If the split between the two levels of the dependent variable is close to 50-50, then both logistic and linear regression will end up ...

Here, the variance of Y seems to increase when X increases. As Y represents the number of products, it always has to be a positive integer. In other words, Y is a discrete variable.
