WebMar 12, 2015 · Probably the most commonly used goodness-of-fit measure is the coefficient of determination (aka the R2 value). The formula is: where: Here, yi refers to your input y-values, fi refers to your fitted y-values, and ̅y refers to the mean input y-value. It's very easy to compute: WebThe ordinal Package I The ordinal package provides two main functions: 1. clm for cumulative link models (including ordered logit and probit). 2. clmm for mixed CLMs – same thing but with random slopes and intercepts. I CLMs are more flexible than ordered logit and probit because they allow you to specify some effects as nominal. 35 / 38
