Reliable Confidence Intervals for Software Effort Estimation
This paper deals with the problem of software effort estimation through the use of a new machine learning technique for producing reliable confidence measures in predictions. More specifically, we propose the use of Conformal Predictors (CPs), a novel type of prediction algorithms, as a means for providing effort estimations for software projects in the form of predictive intervals according to...
متن کاملA SAS® Macro to Calculate Exact Confidence Intervals for the Difference of Two Proportions
When comparing two proportions, it is often desirable to have more information than simply the p-value from a hypothesis test. The SAS® procedure FREQ provides both an approximate and an exact p-value, as well as an approximate confidence interval for the ratio of the two proportions. Calculation of the difference of two proportions and any confidence interval for this difference, however, must...
متن کاملNonsymmetric Bootstrap Confidence Intervals Using SASlIML® Software on a PC
In this paper, PC SAS/IML® modules are developed which calculate percentile method confidence intervals and vanants. The modules will work on distributions of parameters generated by any Monte Carlo technique, Including the bootstrap.
متن کاملHow confidence intervals become confusion intervals
BACKGROUND Controversies are common in medicine. Some arise when the conclusions of research publications directly contradict each other, creating uncertainty for frontline clinicians. DISCUSSION In this paper, we review how researchers can look at very similar data yet have completely different conclusions based purely on an over-reliance of statistical significance and an unclear understand...
متن کاملProbabilistic Intervals of Confidence
Abstract: High accuracy should not be the only goal of classification: information concerning probable alternatives diagnoses, probability of these diagnoses, evaluation of confidence in classification, are also important. Neural models are used just to obtain the winner class but do not provide any justification for their recommendations – they work as black boxes. A method which determine con...
