Data Analysis with R

Corona and Global Supply Chain  Arunachalam Rajagopal During the year 2018-19, approximately 70 percentage of Indian foreign trade is accounted for by the top 20 countries. The United States of America, on top of the list being the first accounts for 10.42 percentage of total foreign trade by India during this period.   Second in the list, as shown in Table 1 is China which accounts for 10.31 percentage of the total foreign trade. It is worth noting that the top ten countries, as per the list shown in Table 1, accounts for 50 percentage of the total trade value in dollar value. Table 1: Foreign trade - Top 20 country’s list Source: Government of India Commerce Ministry website Global trade routes The global trade routes when considered in in a very broad manner are Trans-Pacific, Asia-Europe, and Trans-Atlantic. The more specific major global trade routes are shown in Table 2. Many of the countries involved in major trade routes are infected wi...

Electricity Generation Forecast using Artificial Neural Network with R  Arunachalam Rajagopal The artificial neural network (ANN) is based on the concept of machine learning. ANN attempts to mimic the human brain into the machine (computer). ANNs attempt to learn the patterns that are exhibited in the training dataset (input - independent variable and output - dependent variable). Then based on the previous learning, ANN attempts to give generalized solution for the total dataset. The solution could be forecast in a time series dataset or causal regression model. It could also be used for classification of the dataset like what is done in a discriminant analysis or logistic regression. Artificial neural network (ANN) are data-driven and self-adaptive. There is no need to make any a priori assumption on the input data. The neural network model is formed in an adaptive manner based on the pattern exhibited by the dataset. The artificial neural network is ...
