runApp {quadraticSD}

Visualizing the SD using a Quadratic Curve

Description

Given a dataset, the user is invited to utilize the Empirical Cumulative Distribution Function (ECDF) to guess interactively the mean and the mean deviation. Thereafter, using the quadratic curve the user can guess the Root Mean Sqaured Deviation (RMSD) and visualize the Standard Deviation (SD). For details, see Sarkar and Rashid (2019), Have You Seen the Standard Deviaiton?, Nepalese Journal of Statistics, Vol. 3, 1-10

Usage
