There are 11 main methods that can be used when working with a principal component analysis object in Python.
Here is a table listing all the methods that can be applied on the PCA object.
| fit() | Fit the model with X. |
| fit_transform() | Fit the model with X and apply the dimensionality reduction on X. |
| get_covariance() | Compute data covariance with the generative model. |
| get_feature_names_out() | Get output feature names for transformation. |
| get_params() | Get parameters for this estimator. |
| get_precision() | Compute data precision matrix with the generative model. |
| inverse_transform() | Transform data back to its original space. |
| score() | Return the average log-likelihood of all samples. |
| score_samples() | Return the log-likelihood of each sample. |
| set_params() | Set the parameters of this estimator. |
| transform() | Apply dimensionality reduction to X. |
