spatial statistics for spectral indices and land cover composition

I have a created a series of spectral indices for a sample of pixels. I have also determine land cover proportions from arial photography (grass, trees, water, built and bare earth)

I am looking for statistical methods for analysing the indices against land cover proportions. Currently, I have completed descriptive statistics and as the datasets are non-parametric, I have used Mann-Whitney and Kruskal-Wallis tests to compare medians.

Does anyone have any suggetions for follow-up methods for deeper analysis?
