Hi,

I have an array with precipitation data and other with burned area. I don't
have experience with curve_fit. I read my data and plot the points for each
precipitation and burned area. Then I use:
popt = curve_fit(non_linear_model, preciamz,areaqamz)

and I had:
/home/conrado/FOCOS_2003_2024/NELSON/VER_NC_SHP/ler_csv_areaq_prec_plota.py:69:
OptimizeWarning: Covariance of the parameters could not be estimated

Please how can I resolve this error.

Thanks,
Conrado
