Equation:
Multiple regression: Y = b0 + b1*X1 + b2*X2 + … +bnXn
compare to Simple regression: Y = b0 + b1*X

In English:
Y is the predicted value of the dependent variable
X1 through Xn are n distinct independent variables
b0 is the value of Y when all of the independent variables (X1 through Xn) are equal to…[Read more]

Find a line that models the relationship between a dependent variable and an independent variable.

Equation:
y = α + b*x

In English: y is the dependent variable: what we are trying to predict, α is a constant: y at x = 0, b is a coefficient: slope of the line, x is the independent variable: what we think predicts y…[Read more]
