Imagine regression analysis using Excel, Geogebra, Graph, etc. except it gets done much faster (sciplot-edition)

• Get started

NOTE: The program Graph is simply used for testing the results of the regression model & coefficient of determination R^2

RegressionAnalysis_sciplot

Regression analysis program utilizing sciplot to plot the results. Using .txt files as input, the following can be made:

• Regression model(s) and coefficient(s) of determination R^2
  1. Linear
  2. Exponential
  3. Logarithmic
  4. Power
  5. Second-degree polynomium [degree of polynomium adjustablue in code]
• Plotting
  1. Regression models
  2. Residual plot hereof
• Other statistical descriptors (x- and y-axis respectively
  1. Domain & range; quarters of dataset
  2. Average/mean
  3. Variance, standard deviation, sample standard deviation
• Correlation coefficient r of ONLY linear regression model

RegressionAnalysis_sciplot.cpp imports the following files:

• ...sciplot-master/sciplot/sciplot.h
• [FILENAME].txt

The format of this [FILENAME].txt can be seen with the available example datasets. Compatible data (in the current state of the program) can be boiled down to the following datapoints:

x	y
1	1
1,	1
1.0	1.0
1.0,	1.0
1,0	1,0
1,0,	1,0

NOTE: Do not forget to enter SPACEBAR or TAB in between the x- and y-axis for each line in [FILENAME].txt

PRO TIP regarding datasets from excel, geogebra, graph, etc

1. DATASET -> CTRL + C
2. REPOSITORY -> Make/insert .txt file
3. .txt file -> CTRL + V

You're welcome

To run regressionAnalysis_sciplot.cpp

Install gnuplot

Once this is installed, you'll be able to run the executable attached to the release "1.0 Sciplot-edition"

https://sourceforge.net/projects/gnuplot/

NOTE: Make sure to set {...\gnuplot\bin} as an environment variable

Install sciplot

https://github.com/sciplot/sciplot

Include the downloaded "sciplot-master" following under "include Directories": {...\sciplot-master}
