How to Simulate Multiple Samples From a Linear Regression Model

In this blog post, we will learn how to simulate multiple samples efficiently. In order to keep the discussion, easy we have simulated a single sample with ‘n’ number of observations, and ‘p’ amount of variables. But in order to use the Monte Carlo method to approximate the distribution sampling of statistics, one needs to simulate many specimens with the same regression model.

The data steps in SAS in  most blogs have 4 steps mentioned for so. However, to simulate multiple samples, put DO loop around these steps that will generate, the error term and the response variable for very observation made in the model.

The Most Interesting Scientific Fact About Numbers a Data Scientist can Know

Are you a non-data person? Do you think numbers are unnecessarily complex and are better to stay away from? When asked to calculations do you feel a little of sleepiness setting in? Then this would come as a surprise to you that our brains originally think in numbers. To be more precise, our brains actually think in the Logarithm Scale instead of thinking in the additive scale. To put it simply our brains understand better in terms of proportions than in differences.

So, how would our brains approach differences in numbers? We think almost automatically that the difference between 1 and 2 is greater than the difference between 3 and 2 and so forth.

Here in this picture the first diagram is of the Logarithmic scale while the second one is of the additive scale. Both these scales have their utility in real life situations but while our perception bias associated with the Logarithmic scale often create some problems.
