This study uses a secondary dataset consisting of daily stock price and oil price from January 2007 to December 2014.
The secondary dataset, daily 10 km gridded climate dataset for Canada 1961-2003, was obtained from the website (http://www.agr.gc.ca/nlwis-snite/index_e.cfm).cfm
In their study, the authors compiled a secondary dataset of peat thickness measurements to assess the accuracy of existing WI and MoA maps.
The individual country report was more focused on the mean score and percentages of students' performances by certain demographic characteristics such as gender and school location based on the secondary dataset (e.g., Ministry of Education 2013).
Empirical data from the secondary dataset of GEFRI-contributed entrepreneurial profiles were used to refine and corroborate the coding and thematic categorization of the primary data and to reinforce the validity of findings through partial triangulation.
We assume that data are collected from sensors and denote the complex vector of the primary data by x, with dimension N. As customary, we assume that a secondary dataset, x l, l = 1,…,L, is available, that each of them does not contain any useful signal, and shares the same covariance matrix with the primary data.
The desired 10 km annual mean temperature dataset could be obtained based on the data of maximum and minimum temperature.The primary dataset was based on the period of 1979 to 2009 while the secondary dataset was based on the period of 1961 to 2003.
The expression profiles of a subset of 20 genes (representative of secreted factors and their receptors from the IPA networks) across samples representing normal and tumour epithelial cells were then selected to create a secondary dataset.
The ECLS-B is a restricted-use secondary dataset.
A cross-sectional study using a secondary dataset was carried out.
Second, this is a secondary dataset research based on three different data files.
