## Assignment Description

**Homework 2 **

**IE 7275 Data Mining in Engineering **

**Task
1: Tutorial **

^{•} Reading chapter “Principal
components and factor analysis.”

### Task 2: Perform principal component analysis

• Input the raw data matrix to fa.parallel() function to determine the number of components to extract

• Input the raw data matrix to principal() function to extract the components. If raw data is input, the correlation matrix is automatically calculated by principal() function.

• Rotate the components

• Compute component scores

• Graph an orthogonal solution using factor.plot()

• Interpret the results

### Task 3: Perform factor analysis

• Input the raw data matrix to fa.parallel() function to determine the number of components to extract

• Input the raw data matrix to fa() function to extract the components. If raw data is input, the correlation matrix is automatically calculated by fa() function.

• Rotate the factors

• Compute factor scores

• Graph an orthogonal solution using factor.plot()

• Graph an oblique solutions using fa.diagram()

• Interpret the results

### Task 4: Perform multidimensional scaling

• Input the raw data matrix to fa.parallel() function to determine the number of components to extract

• Input the raw data matrix to cmdscale() function to perform multidimensional scaling. cmdscale() function which is available in the base installation performs a classical multidimensional scaling.

• Graph an orthogonal solution using factor.plot()

• Interpret the results
