What is Linear Regression?Lekulana Kolobe
Linear regression is linear in that it guides the development of a function or model that fits a straight line -- called a linear regression line -- to a graph of the data. This line also minimizes the difference between a predicted value for the dependent variable given the corresponding in...
In simple linear regression, if the coefficient of x ispositive, wecan conclude that the relationship between the independentand dependentvariables is positive. Here, if the value ofxincreases, the value ofyalso increases. Now, if the coefficient of x is negative, wecan say that the relationship...
Linear regression is a kind of statistical analysis that attempts to show a relationship between two variables. Linear regression looks at various data points and plots a trend line. Linear regression can create a predictive model on apparently random data, showing trends in data, such as in canc...
Linear regression analysis is used to predict the value of a variable based on the value of another variable. The variable you want to predict is called the dependent variable. The variable you are using to predict the other variable's value is called the independent variable. This form of ...

In general, a linear regression model can be a model of the form yi=β0+K∑k=1βkfk(Xi1,Xi2,⋯,Xip)+εi, i=1,⋯,n, wheref(.) is a scalar-valued function of the independent variables,Xijs. The functions,f(X), might be in any form including nonlinear functions or polyno...
The intercept is the constant term in the regression equation, representing the expected value of the dependent variable when all independent variables are zero. 6. Residual A residual is the difference between the dependent variable’s observed value and the regression model’s predicted value. Resi...
