Interpretasi dari prediktor dan / atau respons yang diubah log

Saya bertanya-tanya apakah itu membuat perbedaan dalam interpretasi apakah hanya dependen, baik dependen dan independen, atau hanya variabel independen yang ditransformasikan log. Pertimbangkan kasus log(DV) = Intercept + B1*IV + Error Saya bisa menafsirkan IV sebagai peningkatan persen tetapi...

Menghitung pengulangan efek dari model lmer

Saya baru saja menemukan makalah ini , yang menjelaskan bagaimana menghitung pengulangan (alias reliabilitas, alias korelasi intraclass) dari pengukuran melalui pemodelan efek campuran. Kode R adalah: #fit the model fit = lmer(dv~(1|unit),data=my_data) #obtain the variance estimates vc =...
