Guidelines for interpreting correlation coefficient r :
  0.7<|r|≦1        strong correlation
  0.4<|r|<0.7     moderate correlation
  0.2<|r|<0.4     weak correlation
  0≦|r|<0.2         no correlation

    Entertainment-- I'm looking at data from the coronavirus outbreak.
    Just now, with info available the power regression gives a slightly higher r
    than the exponential equation. There is a large difference between the two extrapolations of number of confirmed cases projecting to 40 days.

    400,000 for the exponential equation and 140,000 using the power equation.
    We'll see, and lets hope the curve breaks quickly.

    It would be great if we could define multiple independent variables.

    Purpose of use
    College project involving fitting curve to test data
    Comment/Request
    This is a nice tool, but I''m not able to use it for my project because I can''t adjust the y-axis, nor the x-axis. I''m dealing with test data where 0<= y <= 5, and 1<=x<=99. The curve being generated for my test data is entirely useless since the y-axis goes up to 1400.

    I would absolutely love this if I could adjust the scale.
