The tool calculates the Linear equation, R, p-value, outliers and the adjusted Fisher-Pearson coefficient of skewness. After checking the residuals' normality and priori power, the program interprets the results. Then, it draws a histogram, a residuals QQ-plot, a residuals x-plot, and a distribution chart.

Right-tailed F test. Checks if the entire regression model is statistically significant. Why?
