Machine Learning (Linear Regression) By:- Aditya Sir | Linear Regression in Python смотреть онлайн

Hello and welcome to my channel ,
Today "Aditya sir" will be talking about Linear Regression. We show you also how implement a linear regression in excel.

Linear regression attempts to model the relationship between two variables by fitting a linear equation to observed data. One variable is considered to be an explanatory variable, and the other is considered to be a dependent variable.

Dependent Variable – Variable who’s values we want to explain or forecast
Independent or explanatory Variable that Explains the other variable. Values are independent.
Dependent variable can be denoted as y, so imagine a child always asking y is he dependent on his parents.
And then you can imagine the X as your ex boyfriend/girlfriend who is independent because they don’t need or depend on you. A good way to remember it.
Used for 2 Applications To Establish if there is a relation between 2 variables or see if there is statistically signification relationship between the two variables-

• To see how increase in sin tax has an effect on how many cigarettes packs are consumed
• Sleep hours vs test scores
• Experience vs Salary
• Pokemon vs Urban Density
• House floor area vs House price
