Learn things especially in coding need a practice. Lets put it into work then. Today we are going to enthusiatly dig deeper between what is VAR and what is structural VAR.

PhD is when you are trying to explain something and get so enthusiatly love about it.

When we discuss a lot about SVAR, there is so many words mentioning Cholesky decomposition, what is it? And why it is important to know about Cholesky decomposition, so let's say it's actually a way to find the other format of the triangle in upper and lower. 

Lets say 

\( A = L . L^{T} \)

Or Matrix x equal with decomposition L multiply by L transpose. 

The picture is here

After I learned about Cholesky decomposition, I feel like I got some superpower.

Recent news

Correlation coefficients are used to measure how strong a relationship is between two variables. There are several types of correlation coefficient, but the most popular is Pearson’s. Pearson’s correlation (also called Pearson’s R) is a correlation coefficient commonly used in linear regression. If you’re starting out in statistics, you’ll probably learn about Pearson’s R first. In fact, when anyone refers to the correlation coefficient, they are usually talking about Pearson’s.
