ANLY482 AY2016-17 T2 Group13 - Project Findings
Before embarking on an Exploratory Data Analysis (EDA, the data had to be transformed for further analysis. Viewing the data based on 2D HS codes alone was insufficient because aggregated categories included too many possible unrelated items in the same category. These were the data cleaning steps that were attempted:
All the .csv files were placed in a folder to ensure that concatenation of csv files would only be among datasets that we will be using for the project. Then the “copy *.csv” function was used to combine all the csv folders together though leaving the original folders intact.
R was also used to combine folders together. This was done by loading the .csv files into variables. After which, the “rbind” function was used to combine the datasets together.
Many of the columns in the raw data file did not have values in them. Due to this, we decided to remove the columns in Microsoft Excel because they would not have been useful to our analysis.
Above is the data set after removing the unnecessary columns. Variables containing weight appeared in 4d and 6d data and were not as apparent for 2d data. Due to this, we decided to leave the variables for the dataset.
We received the names for 18 sectors that the DIT focuses on, listed below.
