Data mining and extraction – Specialised techniques are used in drawing data from complex and at times very large databases with the principal aim of identifying predictive information as well as underlying pattern.

Data Processing – We offer data entry, cleansing and analysis services. Data entry is conducted using the very latest versions of statistical software packages such as STATA, SPSS, Epi-Info, Excel, Nvivo, Minitab and CS-Pro. Data Cleansing ensures data quality through checking of consistency and accuracy of records. Specialised statistical techniques are used in the processing of data to generate meaningful information that may be used in decion making. Specific approaches used here include:
