They then randomly assigned the children to three experimental groups, single model, multiple model, and control. Please explain these models.

 In the context of an experiment involving single model, multiple model, and control groups—especially with children—these typically refer to different instructional or observational learning conditions. Here's what they generally mean:

1. Single Model Group

  • Children observe one model (person) performing a task or behavior.

  • The model could be a teacher, adult, or peer demonstrating the desired behavior once or consistently.

  • Purpose: To see how learning occurs from a single source of influence.

Example: A child watches a single adult demonstrate how to solve a puzzle.

2. Multiple Model Group

  • Children observe multiple models (e.g., two or more people) performing the same task.

  • The models may demonstrate similar or varying approaches.

  • Purpose: To assess how observing different perspectives or repetitions influences learning or behavior.

Example: A child watches two adults solve the same puzzle using slightly different strategies.

3. Control Group

  • Children do not observe any model performing the task.

  • This group either receives no intervention or a neutral activity.

  • Purpose: Acts as a baseline to compare how much learning occurs without modeling.

Example: A child is given the puzzle without seeing anyone solve it.

Two-Step System GMM (Generalized Method of Moments)

 The Two-Step System GMM is a dynamic panel data estimation technique designed to address: Endogeneity of explanatory variables Unobserved heterogeneity (fixed effects) Autocorrelation and heteroskedasticity It improves upon simpler estimators (like OLS or FE) and is particularly useful when the model includes lagged dependent variables . ⚙️ System GMM: The Basics Developed by Arellano & Bover (1995) and Blundell & Bond (1998) , System GMM combines: Difference GMM (Arellano & Bond, 1991): First-differences the model to remove fixed effects and uses lagged levels as instruments . Level GMM (Blundell & Bond) : Uses lagged differences as instruments for the level equation to improve efficiency. 🧮 The Dynamic Panel Model A typical dynamic panel data model is: y i t = α y i t − 1 + β X i t + μ i + ε i t y_{it} = \alpha y_{it-1} + \beta X_{it} + \mu_i + \varepsilon_{it} y i t ​ = α y i t − 1 ​ + β X i t ​ + μ i ​ + ε i t ​ Where: y...

Shodhganaga vs Shodhgangotri

  Shodhganga and Shodhgangotri are both initiatives by the INFLIBNET Centre (Information and Library Network Centre) in India. They aim to promote research and knowledge sharing in the academic community but serve different purposes. Here’s a comparison: Feature Shodhganga Shodhgangotri Purpose Repository for completed theses and dissertations. Repository for research proposals and synopses. Content Full-text doctoral theses and dissertations submitted by universities. Approved research proposals and synopses of doctoral students. Focus Stage of Research Final stage – after the research is completed. Initial stage – before the research begins. Target Audience Researchers looking for completed, peer-reviewed research work. Scholars looking for examples or ideas for research topics and methodologies. Utility ...

Panel Stationarity Tests: CADF and CIPS Explained

 When dealing with panel data , testing for stationarity (i.e., whether variables have a constant mean and variance over time) is crucial before estimation—especially in macroeconomic and financial studies. Two advanced second-generation panel unit root tests used to check for stationarity while accounting for cross-sectional dependence are: 🔹 1. CADF (Cross-sectionally Augmented Dickey-Fuller) Test 📌 Developed by: Pesaran (2007) CADF is an extension of the Augmented Dickey-Fuller (ADF) test that augments each ADF regression with cross-sectional averages to account for cross-sectional dependence . 🔍 Model Form: For each unit i i i , the CADF regression is: Δ y i t = a i + b i y i , t − 1 + c i y ˉ t − 1 + d i Δ y ˉ t + ∑ j = 1 p ϕ i j Δ y i , t − j + ε i t \Delta y_{it} = a_i + b_i y_{i,t-1} + c_i \bar{y}_{t-1} + d_i \Delta \bar{y}_{t} + \sum_{j=1}^{p} \phi_{ij} \Delta y_{i,t-j} + \varepsilon_{it} Δ y i t ​ = a i ​ + b i ​ y i , t − 1 ​ + c i ​ y ˉ ​ t − 1 ​ + d i ...
