Today we have learnt about creation,inverse,transpose and multiplication of matrices.Then we moved on to regression and residual analysis by taking NSE historical data for NIFTY index for a certain period.Finally we had an introductory idea about how to plot normally distributed curve.
Question 1:
Create two matrices of say size 3 X 3 and select the column 1 from one matrix and column 3 from second matrix. After selecting the columns in objects say x and y merge these two columns using cbind to create a new matrix .
Syntax & Output:
Question 2:
Multiplication of two matrices. The two matrices which were created in the previous question were multiplied and results were seen.
Syntax : z1%*%z2
Output:
Question 3:
Read historical data of NIFTY indices from NSE for the period 1st Dec 2012 to 31st Dec 2012. Find regression and residuals.
Syntax:
Output:
Question 4: Generate a normal distribution data and plot it.
Syntax:
Output:
