Sorry erik for my stupid questions, but for people like me who never learnt programming (nor could find anyone to help me physically around me), i do struggle to even understand the message Maple returns. Anyway, thank you for your patience, and bear with me for more questions. please see the code below, i put in with(Statistics) and with(plots) but there are still errors.

it did not give me what i used to have from copying and pasting data from excel (see working_plot_and_fit.mw)

Erik, i tried the code you suggested, but it still did not return to me the plot,nor the fitted parameters... see attached.

Also, how can i, , import directly from excel columns into the vectors V and C?instead of pasting columns of data into the bracket after vector?

thank you. The previous problem has been solved more or less, i then paste columns of data from my excel (so far still did not figure out how to read directly from excel columns into the Vector).

then i tried the following:

ans1 := Fit(a*x^n+bx+c, V, C, x);

which returned an answer with a and b values

but when i tried

ans2 := Fit(a*x^n+b*x+c, V, C, x, output = [parametervalues, residualsumofsquares]);

to get the Rsquared value, the a and b values are different. please see attached. and i dont know how to plot out ans 2.

thank you. The previous problem has been solved more or less, i then paste columns of data from my excel (so far still did not figure out how to read directly from excel columns into the Vector).

then i tried the following:

ans1 := Fit(a*x^n+bx+c, V, C, x);

which returned an answer with a and b values

but when i tried

ans2 := Fit(a*x^n+b*x+c, V, C, x, output = [parametervalues, residualsumofsquares]);

to get the Rsquared value, the a and b values are different. please see attached. and i dont know how to plot out ans 2.

restart: with(plots); with(Statistics);
