About Me

I have over twenty years of work experience in the field of statistics as an Applied Statistician and a Data Scientist. For the last twelve years, I have also been teaching undergraduate college level statistics courses at St Petersburg College.  As a Data scientist, I have developed over the years a strong interest in computational statistics.  I am also interested in teaching data sciences techniques  to students and those interested in using data sciences techniques in their respective fields.   My programming languages of choice are Python and R.  I am also interested in Spark, Databricks, PySpark.

Distribution of the World Cup soccer average attendance since 1970

In this analysis, we are looking at the World Cup average game attendance distribution.  We decided to restrict the data from 1970 onward to give an overall distribution of relatively current attendance data. The analysis proceeds with basic data manipulation in pandas. After the basic data manipulation, we use Seaborn to create the distribution.  From […]
