Explanation Considering a fitted line which is drawn to a scatter plot of two quantitative variables, the residuals can be observed. These residuals are defined as the difference between the actual value and the interpreted value on the straight line. The sum of squares of these residuals is considered as a measurement of the closeness/accuracy of the line. The sum of the squared residuals is always a positive number because there are no negative squares. If the sum of residuals is equal to zero, there should not be any residual on either side of the line. That means every point in the scatter plot is located right on the straight line. Therefore, the relationship between these two variables is said to be 100 % linear, without depending on the direction. Hence, the drawn line represents the relationship between the variables perfectly

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 p…

Please solving problem2 Problem1 We consider a two-period binomial model with the following properties: each period lastsone (1) year and the current stock price is S0 = 4. On each period, the stock price doubleswhen it moves up and is reduced by half when it moves down. The annual interest rateon the money market is 25%. (This model is the same as in Prob. 1 of HW#2).We consider four options on this market: A European call option with maturity T = 2 years and strike price K = 5; A European put option with maturity T = 2 years and strike price K = 5; An American call option with maturity T = 2 years and strike price K = 5; An American put option with maturity T = 2 years and strike price K = 5.(a) Find the price at time 0 of both European options.(b) Find the price at time 0 of both American options. Compare your results with (a)and comment.(c) For each of the American options, describe the optimal exercising strategy.
