Abstract

Multicolinierity between variable predictor in multiple regression is assuming violation  for ordinary least square estimator (OLS). Ridge Regression (RR) and Partial Least Square Regression (PLSR were used to handle the multicolinierity problem. RR modify OLS by adding subjective bias consatant, while PLSR, generalize and combine Principal Component Analisis and multiple regression. The efficiency of these two methods will be compared based on the value of RMSE. This study simulated generating data in different level of multicolinearity, the number of variabel, and number of observation were controlled. This study results that, overall, both method equally efficient.

Abstract

The successful of developing and implementation of information sistem is dependon the user acceptance. SIPADU-STIS is an academic information system that support academic’s bisnis process. Technology Acceptance Model (TAM) will be employed for analysing of SIPADU-STIS system. Validation of TAM model will estimate using Structural Equation Model (SEM). The model shows that SIPADU-STIS has a high user’s acceptance .
