data1d

data1d: Simulated univariate one-dimensional datasets for demonstrating continuum-level statistical analysis.

Overview

These three datasets were generated to illustrate the basic concepts of random field theory-based statistical inference. Each dataset contains ten scalar 1D trajectories, each with 101 nodes.

• Datasets A and B represent one-sample (or paired) designs.
• Dataset C represents a regression design, with the following independent variable values: [50, 53.75, 57.5, 61.25, 65, 75, 78.75, 82.5, 86.25, 90]

Loading and viewing the data (MATLAB)

file_name = 'datasetA.h5'; 
y = hdf5read(file_name, '/y'); 
plot(y)

Loading and viewing the data (Python)

import tables 
from matplotlib import pyplot 

file_name = 'datasetA.h5' 
file_id = tables.openFile(file_name, mode='r') 
y = file_id.getNode('/y').read() 
file_id.close() 

pyplot.plot(y.T) 
pyplot.show()
