This is suitable for time-interval measurements at 1 Hz, for example from a time-interval-counter measuring the 1PPS output of two clocks. when only one input parameter is given, phase data in seconds is assumed when no rate parameter is given, rate=1.0 is the default when ... WebStep-by-step explanation. Principal component analysis yields a figure depicting the cumulative explained variance ratio of the data (PCA). Number of components on the x-axis, and total variation explained by components on the y-axis. The ratio of cumulative explained variance becomes larger as the number of components grows larger.
