Correlation

Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.

In economics, utility is a measure of satisfaction or usefulness. The utility of wealth could therefore be thought of as how happy you are as a function of the amount of wealth you possess. When applied to economic measurements, the word "marginal" describes the change corresponding to an increase in the measured quantity. The marginal utility of wealth is how much your happiness increases as your wealth increases. The Law of Diminishing Marginal Utility states that as you consume more, your marginal utility decreases; that is, the more you have of something, the smaller the impact getting more of it affects your happiness. If w is your wealth, and T(w) is your utility of wealth, your marginal utility of wealth at w is M(w) = lim h→0 T(w+h)-T(w) h and the rate at which your marginal utility of wealth is changing at w is M (w+h) — M(w) h C(w) = lim h→0 Suppose w is measured in 10s of thousands of dollars, and T(w) wealth. - 300w w + 1 is the utility of your (a) Find a closed form…
