I was going through the Coursera "Machine Learning" course, and in the section on multivariate linear regression something caught my eye. Andrew Ng presented theNormal Equationas an analytical solution to the linear regression problem with a least-squares cost function. He mentioned that in some c...
Linear regression gives an equation which is of the form Y = mX + C, means equation with degree 1. However, logistic regression gives an equation which is of the form Y = eX + e-X Coefficient interpretation In linear regression, the coefficient interpretation of independent variable...
Residuals are normally distributed- In addition to having equal scatter, in the standard linear regression model, the residuals are assumed to come from a normal distribution. This is commonly assessed using a QQ-plot. Linear relationship between predictorsand response- The relationships must be linea...

The regression equation here is given by the formula When the joint distribution of X and Y is normal, both regression lines y = u(x) and x = v(y) are straight lines. If the regression of Y on X is not linear, the last equation becomes a linear approximation of the true regression...
Linear regression, also known as simple linear regression or bivariate linear regression, is used when we want to predict the value of a dependent variable based on the value of an independent variable. For example, you could use linear regression to understand whether exam performance can be ...
