• Get started

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

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:

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

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

You're welcome
