Confidence interval calculator for fuzzy random regression

The software tool namely Confidence Interval Calculator (CIC) presented in this paper is designed to compute confidential interval of fuzzy random regression (FRR) model. FRR model uses fuzzy random input-output data to construct confidential interval for prediction. Manual calculation by hand of FRR however requires lengthy time to compute the result. Hence, CIC is introduced to alleviate computational difficulties and to reduce the computational time. The tool provides a function to capture input (fuzzy random) data and to calculate the expected value, and the variance. Technical formulation is embedded in the tool which enables the tool to compute the result correctly. The solution of a technical problem is described with numerical example.
