#perform two-way ANOVA
model = ols('height ~ C(water) + C(sun) + C(water):C(sun)', data=df).fit()
sm.stats.anova_lm(model, typ=2)

	           sum_sq	  df	      F	   PR(>F)
C(water)	 8.533333	 1.0	16.0000	 0.000527
C(sun)	        24.866667	 2.0	23.3125	 0.000002
C(water):C(sun)	 2.466667	 2.0	 2.3125	 0.120667
