I have a set of data and I plotted (scatter plot) those on log-log scale. Then I fitted a trendline to the data. NOw I need to determine the slope and y intercept of the fitted trendline. How to detrmine that?
Matlab script used:
p=[......];
q=[.....];
scatter(p,q);
set(gca,'XScale','log');
set(gca,'YScale','log');
b = polyfit(log(p), log(q), 1);
qfit = exp(b(2)) .* p.^b(1);
hold on
plot(p, qfit)
hold off
