The Extraction Of Factors And Factors - 941 Words

The extraction of factors helps to determine the loading of factors. The factor loading matrix is shown below and is estimated with two common factors. The first column of the matrix depicts the first unrotated factor and it can be analysed that the first factor puts maximum and approximately equal weights to the first, second and fifth variable. And, it puts the minimum weight to the third variable, electricity. On the other hand, the second unrotated factor places the least weights to the first and second variable, while putting the highest weight to the third variable. Factor Loadings = Scatter plot of Unrotated Factor Scores The Figure. 15 shows the scatter plot of Score2 vs. Score1. It is clear that the 15th observation has the†¦show more content†¦Selecting an appropriate rotation is difficult task. Hence, it is preferable to perform both rotations on the factors. Varimax rotation technique results in high loading of each variable on a few number of factors, ideally on one factor and hence resulting in better factor analysis. The Figure. 18 shows the biplot of loadings of varimax rotated factors. It can be seen that in order to bring the loadings close to zero or one, varimax has rotated the axes. The four variables are close to first factor axis. While, the third variable lies approximately on second factor axis. Hence, the results of varimax rotation are satisfactory because most of the variables are near to the factor axis. Figure. 17 Promax rotation can be used incase we are not able to obtain the satisfactory and simple set of factors with an orthogonal rotation. The promax rotation allows the factor axes to have an oblique angle between them. The Figure. 19 shown belows depicts the promax rotation. It can be seen that the variables 1, 2 and 5 are close to the first factor axes and third variable is close to the second factor axis. The data is better accomodated in an oblique rotation. The two latent factors can describe variability of buildings and agriculture, which are having high impact on greenhouse gas emissions.

The extraction process itself is inefficient and the pipeline that has been proposed is subject to many environmental risks. Portions of the pipeline have already been approved and the construction of the pipeline is already begun in some areas. This paper will look at some of the factors associated with tar sands extraction and production of fossil fuels.

Davidson, includes information required to make an informed decision on whether or not to diversify into the Oil and Natural Gas Extraction industry. The Oil and Natural Gas Extraction industry is involved in the processes required to find and extract crude oil and natural gas. The Oil and NaturalRead MoreEnergy Costs687 Words   |  3 Pagesthe future of energy extraction in terms of costs.it will also look at how technological improvement have impacted energy extraction even in the wake of the depletion of convectional sources. Cost-supply and uncertainty are asymmetrical when it comes to extraction of energy. The cost of energy extraction will determine the supply. The future of energy extraction is quite uncertain since non-renewable energy sources are slowly being depleted. The future of energy extraction is quite uncertain whichRead MoreThe Value Of Kmo For Overall Matrix Essay707 Words   |  3 Pages1 enumerates that the communalities of the selected 36 variables have good reliability and keenly checked that no one variable has low loading, i.e., less than 0.5. Thus finally, the 26 variables are selected for the factor analysis. The appropriateness of the data for the factor analysis is discussed in the following KMO and Bartletts’ test.

NUMBER PLATE EXTRACTION The captured input image has number plate covered by vehicle body, so by this step only number plate area is detected and extracted from whole body of vehicle. The number plate extraction phase influence the accuracy of ANPR system because all further step depend on the accurate extraction of number plate area. The input to this stage is vehicle image and output is a portion of image containing the exact number plate.
