Label | Explanation | Data Type |

Input raster bands | The input raster bands. They can be integer or floating point type. | Raster Layer |

Number of Principal components (Optional) | Number of principal components. The number must be greater than zero and less than or equal to the total number of input raster bands. The default is the total number of rasters in the input. | Long |

Output data file (Optional) | Output ASCII data file storing principal component parameters. The output data file records the correlation and covariance matrices, the eigenvalues and eigenvectors, the percent variance each eigenvalue captures, and the accumulative variance described by the eigenvalues. The extension for the output file can be .txt or .asc. | File |

### Return Value

Label | Explanation | Data Type |

Output multiband raster | The output multiband raster dataset. If all of the input bands are integer type, the output raster bands will be integer. If any of the input bands are floating point, the output will be floating point. If the output is an Esri Grid raster, the name must have less than 10 characters. | Raster |
