The following post is about Short Questions related to Normal and Standard Normal Distribution. Q1: What is a standard normal variable? Ans: The variable $Z=\frac{X-\mu}{\sigma}$ which measures the deviations of variable $X$ from the Average in units of Standard Deviation is called the standard normal variable. Q2: Describe the normal distribution and write down its equation. Ans: The normal distribution is a probability distribution of a continuous random variable (say $X$) which ranges from $-\infty$ to $\infty$....

In this post we will learn about Normality Test for the Error term using (1) Anderson-Darling Test and (2) Shapiro-Wilk test. Normality of error (disturbance) term is a basic assumption for many statistical procedures. For example, In linear regression most of the inferential procedures are based on the assumption of normality of the disturbance term, that is, the disturbance term or error term is assumed to be normally distributed....

A wide scatter of points around the regression line shows that there is still room for further improvement. Including extra variables in the model will map up some of the residual variability remaining after $X$ has been used, while the precision of prediction will thereby be increased. It leads to the concept of Multiple Linear Regression Models. A multiple regression model is a model in which a response variable $(Y)$ is linked to $(p\ge 1)$ explanatory variables $(X_1, X_2, \cdots, X_p)$ and a random departure (disturbance) term $(\varepsilon_i)$....
