Introduction to linear regression:
- Linear Regression is Machine learning algorithm based on supervised learning.
- In regression there are two types of variables i.e, Dependent and independent variables.
- The dependent variable is also known as target variable which we try to predict, and the independent variables, also known as explanatory variables.
- The independent variables are shown conventionally by x; and the dependent variable is notated by y.
- A regression model relates y, or the dependent variable, to a function of x, i.e., the independent variables. This model finds the linear relationship between independent and dependent variable.
- The key point in the regression is that our dependent value should be continuous, and cannot be a discrete value.
- However, the independent variable or variables can be measured on either a categorical or continuous measurement scale
- So, what we want to do here is to use historical data,using one or more of their features, and from that data, make a model.
- We use regression to build such a regression or estimation model.
Types of linear regression:
There are 2 types of linear regression models:
- Simple linear regression
- Multiple linear regression.
