Methods for estimation in software engineering include these principles:

COCOMO, the first version known as COCOMO 81 and the second as COCOMO(TM) II
COSYSMO
Evidence-based Scheduling Refinement of typical agile estimating techniques using minimal measurement and total time accounting.
Function Point Analysis
Parametric Estimating
The Planning Game (from Extreme Programming)
ITK method, also known as Method CETIN
