Abstract
This paper deals with fitting of a parabola and three parameter logistic curve to relate heart output and initial index finger temperature with ambient temperature in human subjects. The coefficients of determination (R2%) between observed and estimated values of heat output and initial index finger temperature were close to 98% indicating the high percentage of variation of the total sum of squares absorbed by the fit of the curves. The superiority of the fitted curves over the other curves have been proved. Thus it is concluded that parabola and three parameter logistic curve may explain the relationships of heat output and initial index finger temperature with ambient temperature more precisely than other curves.
