Using the free, open source R language, scientists, financial analysts, public policy professionals and programmers can build powerful statistical models capable of answering many of their most challenging questions. But, for non-statisticians, R can be difficult to learn-and most books on the subject assume far too much knowledge to help the non-statistician.

R for Everyone is the solution. Drawing on his extensive experience teaching new users through the New York City R User Group, professional statistician Jared Lander has written the perfect R tutorial for everyone who’s new to statistical programming and modeling.

 

This book delves into the language of R and makes it accessible using simple data examples to explore its power and versatility. In learning how to “speak R” you will unlock its potential and gain better insights into tackling even the most complex of data analysis tasks.

R for Everyone Book by Lander – R For Everyone Jared Lander Adjusted R2R2 also indicates how well terms fit a curve or line, but adjusts for the number of terms in a model. If you add more and more useless variables to a model, adjusted r-squared will decrease. If you add more useful variables, adjusted r-squared will increase.

Adjusted R2adjRadj2 will always be less than or equal to R2R2. You only need R2R2 when working with samples. In other words, R2R2 isn’t necessary when you have data from an entire population.

Formula

R2adj=1−[(1−R2)(n−1)n−k−1]Radj2=1−[(1−R2)(n−1)n−k−1]

Where −

  • nn = the number of points in your data sample.
  • R For Everyone Lander kk = the number of independent regressors, i.e. the number of variables in your model, excluding the constant.

Example

Problem Statement:

A fund has a sample R-squared value close to 0.5 and it is doubtlessly offering higher risk adjusted returns with the sample size of 50 for 5 predictors. Find Adjusted R square value.

Solution:

R For Everyone Lander Pearson Sample size = 50 Number of predictor = 5 Sample R – square = 0.5.Substitute the qualities in the equation,

R2adj=1−[(1−0.52)(50−1)50−5−1]=1−(0.75)×4944,=1−0.8352,=0.1648
