Introduction to GLMs

This chapter focuses on logistic regression. You'll learn about the structure of binary data, the logit link function, model fitting, as well as how to interpret model coefficients, model inference, and how to assess model performance.

Modeling Binary Data

Here you'll learn about Poisson regression, including the discussion on count data, Poisson distribution and the interpretation of the model fit. You'll also learn how to overcome problems with overdispersion. Finally, you'll get hands-on experience with the process of model visualization.

Bayangkan Anda dapat menangani data dengan variabel respons yang bersifat biner, cacah, atau kira-kira normal, semuanya dalam satu kerangka. Anda tidak perlu membayangkannya lagi. Inilah kursus Generalized Linear Models di Python! Dalam kursus ini, Anda akan memperluas perangkat regresi Anda dengan model logistik dan Poisson, dengan mempelajari cara melakukan fitting, memahami, menilai kinerja model, dan akhirnya menggunakan model untuk membuat prediksi pada data baru. Anda akan berlatih menggunakan data dari studi dunia nyata seperti keracunan populasi terbesar dalam sejarah, perilaku bersarang kepiting tapal kuda, dan perhitungan pesepeda yang melintasi jembatan di New York City.
