Purpose

Congruence serves as a key framework in many leader–follower dyad theories. This paper aims to introduce polynomial regression analysis with response surface methodology (PRA with RSM) as a statistical technique for investigating research questions concerning leader–follower dyadic relationships in the hospitality context.

Design/methodology/approach

First, this paper illustrates the necessity of applying PRA with RSM to more effectively address the research issues related to leader–follower dyadic relationships. Next, this paper presents an overview and the key concepts of PRA with RSM. Critical issues that need to be noted and two recent hospitality leadership studies that have used PRA with RSM are discussed. Third, an empirical example in the hotel context is provided to illustrate the application of PRA with RSM.

Findings

By applying this methodology to the study of hospitality leader–follower dyadic relationships, researchers will be able to address a range of topics related to dyadic theory, such as leader–member exchange and value congruence.

Practical implications

PRA with RSM reveals that congruence effects vary within leader–follower dyads. Industry professionals can promote a better leader–follower fit by incorporating dyadic surveys to understand mutual agreement and perceptions regarding same-workplace phenomena.

Originality/value

The paper addresses the misalignment between leader–follower dyadic theory and the methodology used in hospitality leadership studies.

用多项式回归分析酒店领导者-追随者二元组：批判性反思

目的

一致性是许多领导者-追随者二元理论的关键框架。本文旨在介绍采用响应面法（PRA 和 RSM）的多项式回归分析作为一种统计技术，用于调查有关酒店环境中领导者-追随者二元关系的研究问题。

设计/方法论/途径

首先，本文阐述了应用 PRA 与 RSM 的必要性，以更有效地解决与领导者-追随者二元关系相关的研究问题。接下来，本文介绍了 PRA 与 RSM 的概述和关键概念。讨论了需要注意的关键问题以及最近两项将 PRA 与 RSM 结合使用的酒店业领导力研究。第三，提供了酒店环境中的实证示例来说明 PRA 与 RSM 的应用。

发现

通过将此方法应用于酒店业领导者与追随者二元关系的研究，研究人员将能够解决一系列与二元理论相关的主题，例如领导者与成员的交换和价值一致性。

实际影响

PRA 与 RSM 揭示了领导者-追随者二人组中的一致性效应有所不同。行业专业人士可以通过纳入二元调查来了解双方对同一工作场所现象的共识和看法，从而促进更好的领导者与追随者的契合。

原创性/价值

本文讨论了领导者-追随者二元理论与酒店领导力研究中使用的方法之间的不一致。
