HIV/AIDS cases in an area may be influenced by the adjacent areas. Analysis of factors affecting HIV/AIDS cases can be done through classical Linear Regression. However, spatial regression analysis is a more suitable method to use if location is taken into account. The purpose of this research is to perform a spatial regression analysis on the HIV/AIDS cases in Indonesia in 2021. Spatial depend…
Rainfall is a key component of the water cycle and plays an important role in the ecosystem, especially in tropical regions such as Indralaya Regency. Rain affects various operational aspects in the field, particularly in agriculture and plantations. Binary Logistic Regression and K-Nearest Neighbor (KNN) can be used to classify rainfall events. One common issue in rainfall event classification…
Pada Saat ini, Statistika telah berkembang jauh, seiring dengan ditemukan dan berkembangnya teori peluang. statistika telah memungkinkan untuk melihat jauh kedepan di luar data itu sendiri. Statistika pada tahun 1950-an telah memasuki wilayah pengambilan keputusan melalui proses generalisasi dan peramalan dengan memperhatikan faktor resiko dan ketidakpastian.
Dalam buku ini akan dijelaskan beberapa metode statistika, dimulai dari hipotesis sampai kesimpulan, dan juga membahas prosedur penggunaan SPSS untuk pengolahan data. Semoga dengan membaca buku ini, pembaca tidak hanya akan mampu mengoperasikan software SPSS tetapi juga mampu menentukan metode yang harus digunakan sehingga dapat menghasilkan kesimpulan yang benar
Dalam kehidupan modern, statistik tidak diragukan lagi peranannya, baik dalam kehidupan sehari- hari, dalam ilmu pengetahuan dan penelitian ilmiah, ataupun dalam kegiatan bisnis. Disamping itu, statistik juga mendasari cabang- cabang ilmu baru, seperti ekonometrika, sosiometri, dan psikometri.
