StatApp Green provides a powerfull and portable tool for two-variables polynomial and linear regression calculations for sciences, finance and industrial applications. With an innovative look and design, it provides an easy and intuitive data input view, and results view.
StatApp Green provides the calculation of the following variables:
• Total number of entries
• (x, y) mean, RMS, standard deviation, variance
• Sum(x), Sum(x^2), Sum(y), Sum(y^2) and Sum(xy)
It fits data by using the following linear regression models:
• Linear fit
• Logarithmic fit
• Exponential fit
• Power fit
• Polynomial fit
Providing the value of fit parameters, like A, B and Delta, with the respective errors, and correlation coefficient and chi square.
