Ridge regression is used in linear regression to deal with multicollinearity. It reduces the MSE of the model in exchange for introducing some bias.
Simple regression is used when there is one independent variable. With more independent variables, multiple regression is required.

Linear regression can be used in statistics in order to create a model out a dependable scalar value and an explanatory variable. Linear regression has applications in finance, economics and environmental science.
The word regression is a noun. It cannot be an adjective. When it is paired with another noun, it is a noun adjunct.Examples:"In statistics, regression analysis refers to techniques for modeling and analyzing several variables""Regression techniques are used by psychologists."

Regression is used as a way to break a tie score. It is used as an alternative the "count-back". In a count-back the player who scored the lowest on the 18th hole wins. If they tied on the 18th then you go back to the 17th, 16th etc.When regression is used it's the opposite; the player with the highest score on the last hole wins.
the prefix of regression is regress
Alpha is not generally used in regression analysis. Alpha in statistics is the significance level. If you use a TI 83/84 calculator, an "a" will be used for constants, but do not confuse a for alpha. Some may, in derivation formulas for regression, use alpha as a variable so that is the only item I can think of where alpha could be used in regression analysis. Added: Though not generally relevant when using regression for prediction, the significance level is important when using regression for hypothesis testing. Also, alpha is frequently and incorrectly confused with the constant "a" in the regression equation Y = a + bX where a is the intercept of the regression line and the Y axis. By convention, Greek letters in statistics are sometimes used when referring to a population rather than a sample. But unless you are explicitly referring to a population prediction, and your field of study follows this convention, "alpha" is not the correct term here.
