R: boxplot: draw lines between each subject in case of repeated measurements

I have data where I have measurements of same subjects on 4 different stages. My goal is to make one graph on which there is both a boxplot, as well as the point of each subject with a line connecting each subject between each stage. The end result would be to combine both the graph […]

Iterate Python List of Lists and Remove Final Index of Each Sublist, No Imports

There are a few similar questions to this one but not exactly the same: I want to dynamically decrease a given input array or list of lists. For example: matrix = [[0,1,2], [3,4,5],[6,7,8]] Starting at 0 I need to iterate through and remove the final index – the iterative. So the output I would like […]

How to apply linear regression with fixed x intercept in python?

I’ve found quite a few examples of fitting a linear regression with zero intercept. However, I would like to fit a linear regression with a fixed x-intercept. In other words, the regression will start at a specific x. I have the following code for plotting. import numpy as np import matplotlib.pyplot as plt xs = […]
