Maximum Number of Principal Components

Use the slider or enter a positive integer in the text box to specify the maximum number of principal components to compute. The default value is 10.

If a PCA Data Set is specified, this number cannot be greater than the number of principal components in that data set.

If the value specified in the Cumulative Proportion of Variation to Explain with Principal Components field below is greater than 0, then this number of PCs is evaluated for meeting the proportion of variance explained. If the proportion is not met by the maximum number of principal components specified, then the maximum number of PCs is used.

To Specify the Maximum Number of Principal Components:

Either type the desired value into the text field, or move the slider to the right or to the left to change the value.

Tip: To change the scale of the slider, right-click on the slider and select Rescale Slider from the pop-up menu. Change the upper and/or lower boundaries in the window that appears, to rescale the slider and click OK.
