Panel Data

Panel Data

Panel Data Analysis is a systematic procedure of studying a challenging research objective through multiple sites, periodically tracked over a well-defined time frame. Panel data comprise of repeated observations over a period of time with similar respondents and a set of cross-sectional units. These respondents can be individuals, institutions, expert panel, or any collection of units a marketer can follow over time. A well-structured statistical method has been designed by Chromatus to identify and explore the first-hand information available in panel data sets. Chromatus strongly believes that the time factor is a key feature of our panel data sets, addressing problems of serial correlation and dynamic effects that need to be considered. Panel data sets help in projecting the systematic, overlooked data-points across respondents whose effects are to be measured. Chromatus has successfully overcome the challenges for interpreting estimates from panel data models with the systematic data modelling approach.

Panel data statistical methods are used in estimating the key attributes of the product, concept, services, and to quantify its dynamic linkages, in order to perform valid inferences. For Chromatus, the basis for data models is ordinary least squares applied to suitably transformed data. We have overcome the key challenge in developing a projection model to ensure that statistical output is valid. The key attributes for the Panel Data are –

Invest

Panel data give more informative data, more variability,less co-linearity among the variables,more degrees of freedom and more efficiency.

Invest

Panel data are better able to study the dynamics of adjustment.

protect

Panel data are better able to identify and measure effects that are simply not detectable in pure cross sections or pure time-series data.

Invest

Panel data model allow us to construct and test more complicated behavioral models than purely cross -section or time-series data.

protect

Panel data are usually gathered on micro units, like individuals ,firms and households – More accurate inference of model parameter.

harvest

Constructing and testing more complicated behavioral hypotheses.

protect

Controlling the impact of omitted variables.

harvest

Panel data can minimize estimation biases that may arise from aggregating groups into a single time series.

Divest

Simplifying computation and  statistical inference along with Uncovering dynamic relationship.

WHY WE SHOULD USE PANEL DATA

  • Controlling & Maintaining for individual perspective on any parameter
  • Panel data offers more variations, informative data with more efficiency which is better to study the dynamics of statistical adjustments
  • Panel data helps in identifying and calculating the effects that are not easily analyzed in pure cross-sections data
  • Panel data models allows the marketer to formulate a behavioural hypothesis on purchase, triers, units, for individuals, and for households along with controlling the impact of omitted variables to tap dynamic relationships between the key targeted parameters.
  • Panel data not only helps in simplifying data computation and statistical model inference
  • The key benefit is minimizing biases that may arise from the targeted cluster of groups.
