Principal component analysis explaining total variance

Component	Initial eigenvalues			Factor weight
				Not-rotated			Rotated
	Total	Variance	Cumulative	Total	Variance	Cumulative	Total	Variance	Cumulative
1	5.431	54.31	54.31	5.431	54.31	54.31	5.165	51.65	51.65
2	1.224	12.24	66.55	1.224	12.24	66.55	1.490	14.90	66.55

For each component, with eigenvalue greater than unity, total values, variance and cumulative proportions of initial eigenvalues along with rotated and not-rotated factors weight are reported. Variance and cumulative values are expressed in percentages
