components_param
INTEGER or FLOAT. The parameter to control the number of principal -components to calculate from the input data. If components_param is INTEGER, -it is used for denoting the number of principal components (k) to -compute. If components_param is FLOAT, the algorithm would return enough +components to calculate from the input data. If 'components_param' is INTEGER, +it is used to denote the number of principal components (k) to +compute. If 'components_param' is FLOAT, the algorithm will return enough principal vectors so that the ratio of the sum of the eigenvalues collected -thus far to the sum of all eigenvalues is greater than this parameter. -This value has to be either a positive INTEGER or a FLOAT in the range -(0.0,1.0]
