Abstract
Estimation of time since death from rectal cooling with the help of polynomial regression model is the subject of discussion in the present study. Though in literature various models are available but their complex modeling structure and calculation, restricted their application for real life situations, particularly
in climatic conditions where the room temperature varies between 60.33o to 91.97 o F like of Chandigarh zone of India. The present study is an attempt to provide a suitable model for estimation of time since
death in such conditions. Nonetheless, with the help of polynomial regression model, time since death can be estimated with SE estimate of 0.12947 hours and 0.410277 hours in summer and winter respectively. Moreover, this model has produced smaller confidence and prediction intervals.
