Penentuan Model Evaporasi Menggunakan Kombinasi Analisis Klaster dan Analisis Komponen Utama (Studi Kasus: Data BMKG Kota Medan)

Abstract

ABSTRACT Evaporation is one of the component of hidrology cycle. It can be influenced by intensity of solar radiation, temperature, wind velocity, pressure and humidity. The factors that influence evaporation have differences from one place to another place. Multivariate statistic can be used to analyze evaporation and its factors. Cluster analysis, principal component analysis and regression are used in this research. The results are 2 clusters, they are temperature, wind velocity, intensity of solar radiation and pressure as cluster 1, and humidity as cluster 2. Next result is 2 principal components that each of them has eigen value higher than 1, they are 1.647 and 1.165. Regression model with standard variable Z is ...
