Difference between a Pandas Series and a DataFrame Both DataFrame and series are the two main data structure of pandas library. Series in pandas contains a single list which can store heterogeneous type of data,

df: (R only) A dataframe object. Y: Outcome variable. ID: Identifier of the unit of analysis. Time: Time variable. The command assumes that the time variable is evenly spaced (e.g.: the panel is at the yearly level, and no year is missing for all groups). When it is not (e.g...

V2.0.3 - The Parametric ScottKnott ESD test (v2.x) produces the ranking of treatment means while ensuring that (1) the magnitude of the difference for all of the treatments in each group is negligible; and (2) the magnitude of the difference of treatments between groups is non-negligible...
This diff() function is provided on both the Series and DataFrame objects. Like the manually defined difference function in the previous section, it takes an argument to specify the interval or lag, in this case called the periods. The example below demonstrates how to use the built-in differ...
Each row in the dataframe consists of a pair of measurements. The Bland-Altman plot has the average of the two measures in a pair on the x-axis. The y-axis contains the difference between the two measures in each pair. Add the averages and differences data to the dataframe. ...
