Example 2: Solving the Error Message: contrasts can be applied only to factors with 2 or more levels lm ( outcome ~ col1 + col2 + col3 , # Removing col4 (only one value) from model my_df ) # Call: # lm(formula = outcome ~ col1 + col2 + col3, data = my_df) # # Coefficients: # (Intercept) col1 col2 col3B col3C # 6.5019 0.9351 -1.9218 2.4447 -3.5153 m <- mlogit(CHOICE ~ PRICE + GreenStatement + Certification + MediumBrand + HighBrand, SP1, choice = "CHOICE", shape = "long", alt.levels = "STR") but get the error "contrasts can be applied only to factors with 2 or more levels". A factor of single level can not be applied contrasts to, since any kind of contrasts would reduce the number of levels by 1. By 1 - 1 = 0 this variable would be dropped from the model matrix. Well then, can we simply require that no contrasts be applied to a single-level factor? No. All contrasts methods forbid this: When fitting models using lm and glm, sometimes you can get a mystery error that says that "contrasts can be applied only to factors with 2 or more levels". This function helps trouble shoot this error when it appears by helping to find the problematic errors. Amazing details are found in the StackOverflow where this function comes from.
