I am trying to assess the fit of an exponential equation to a set of data.
I fit the data to an equation using leasqr.m but I want to calculate the
chi-squared value and complete a chi-square test.
if:
f = computed values
y = observed values
I have tried using chisquare_test_homogeneity(f,y,c)
Not sure what c is, so I entered the x array used for leasqr.m
What I receive in return though is:
NaN
NaN
36
36 is the correct degrees of freedom.
What am I missing?
