Estimation of Missing Values in Longitudinal Data Sets Using Regression Methods in Biological Research

G. Tamer KAYAALP and Fatma CEVYK

Abstract:
In biological researches long period data sets were called longitudinal data. But statistical analysis cannot be applied when one or more observations are missing. For the estimation of missing values in longitudinal data sets, regression methods were used. The records from 30 water temperature value (3 station x 10 water temperature at different months) were taken. At the end estimated values for incomplete observations were similar to the model for the full completed observations. This results showed that the regression method for the incomplete observations can be used in similar cases by researchers.
