which is better cubic or quadratic curve? what model does it need based on the curve and the cubic term? can you subtract cubic terms in a growth curve model which term should linear latent curve models add what makes latent curve fit better why does a cubic growth curve have better fit why quadratic growth curves are better is a cubic latent growth curve the same as quadratic can you add a cubic term to a linear model what type of term makes a lgc more fitting what does the cubic term to the latent growth curve mean will a latent growth curve model always have better fit? which model of latent growth curve has best fit does a cubic curve always have better fit does a cubic growth curve always have better fit which curve is best fit a quadratic or cubic term which model has more fitting curves quadratic or cubic when you add a cubic term to a latent growth curve, the fit will always improve? when adding a cubic term to the latent growth curve, the fit will always improve why should latent growth curves be used? do cubic terms increase the goodness of fit
