Model performance of the partial least squares method (PLS) alone and bagging-PLS was investigated in online near-infrared (NIR) sensor monitoring of pilot-scale extraction process in Fructus aurantii. High-performance liquid chromatography (HPLC) was used as a reference method to identify the active pharmaceutical ingredients: naringin, hesperidin and neohesperidin. Several preprocessing metho...

In many domains (marketing, social sciences, etc.) the variables of interest are often not directly observable. Complex causal relationships between such latent variables may be modeled by means of Structural Equation Models (SEM). Two different methodologies exist for the estimation of such models: SEM-ML (Maximum Likelihood Approach to Structural Equation Models), also known as LISREL (Linear...

This study aims to test the effect of social media marketing activities and brand ambassadors on awareness. The sample used was 245 undergraduate students who were selected using convenience sampling. Data taken a questionnaire analyzed Partial Least Square-Structural Equation Modeling (PLS-SEM). results this indicate that have positive influence

Genetic algorithm and partial least square (GA-PLS) and kernel PLS (GA-KPLS) techniques were used to investigate the correlation between retention indices (RI) and descriptors for 117 diverse compounds in essential oils from 5 Pimpinella species gathered from central Turkey which were obtained by gas chromatography and gas chromatography-mass spectrometry. The square correlation coefficient lea...

Muslims are required to consume halal products. One of the products consumed by is cosmetics. Based on Zap Beauty Index (2020) survey, it was found that 49.5 percent consumers did not pay attention labels when buying This study aims analyze determinant factors purchase intention cosmetics in Bogor Regency taking a sample 100 respondents. The sampling method purposive-sampling and analyzed using...

Is the impact of sales promotion on consumer perception mediated by its hedonic and utilitarian benefits in the context of Indian consumers?  Is gender having a moderating impact on the relationship between the benefits of sales promotion and consumer perception?  Authors examined both questions using a partial least square structural equation modeling (PLS-SEM). Findings revealed that hedonic ...

For the purpose of exploring and modelling the relationships between a dataset and several datasets, multiblock Partial Least Squares is a widely-used regression technique. It is designed as an extension of PLS which aims at linking two datasets. In the same vein, we propose an extension of Redundancy Analysis to the multiblock setting. We show that PLS and multiblock Redundancy Analysis aim at...

Composite-based methods like partial least squares (PLS) path modeling have an advantage over factor-based methods (like CB-SEM) because they yield determinate predictions, while factor-based methods’ prediction is constrained in this regard by factor indeterminacy. To maximize practical relevance, research findings should extend beyond the study’s own data. We explain how PLS practices, derivi...
