Curve fitting

1)Calculate all 4 business moments using pen and paper for the below data set?   What is the significance of expected value when simple mean (Sum of all observations/number of observations) is already in place? Simple Mean The "average" number found by adding all data points and dividing by the number of data points.…

1. Why there is a difference in the formula of variance for population and sample? (σ2)=∑(X−μ)2/N , Variance of a population (s2)=∑(X−μ)2/(N-1), Variance of a sample μ is the mean value of corresponding sample or population. N is the number of elements in the data set. The purpose of…

Introduction:  Parsing, syntax analysis, or syntactic analysis is the process of analyzing a string of symbols, either in natural language, computer languages or data structures, conforming to the rules of a formal grammar. The term parsing comes from Latin pars (orationis), meaning part (of speech). Parsing in…

Introduction to Optimization: Optimization is the process of making something better. In any process, we have a set of inputs and a set of outputs as shown in the following figure. Optimization refers to finding the values of inputs in such a way that we get the “best” output values. The definition of…

Introduction to Curve Fitting: Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth"…

SIMPLE PENDULUM A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force acting…

Robotic Arm: Introduction: Robots play a very significant role in todays world. The Application of robots has been drastically increased over the last couple of years and it now has a strong influence in Automotive, Biomedical, Nuclear and Aviation Industries. There are different types of robots that perform various functions…
