- A dataset follows a simple regression model. If the y intercept and slope are given as 500 and 250, respectively, predict the value of y if X is 1.What do you mean by “goodness-of-fit” in regression analysis; how it is determined in linear regression?Consider the linear regression models. The p-values are shown in parenthesis.Model 1 Y = 123.2 + 0.89X1(0.0005) (0.00001)R2 = 0.600Model 2 Y = 40.1 + 0.14X2 + 0.61X3(0.003) (0.008) (0.0004)R2 = 0.825Model 3 Y = -1.7 + 2.57X1 - 1.78X2(0.006) (0.1) (0.2)R2 = 0.876Where Y are the number of trips, X1 is the total employment, X2 is the industrial employment, X3 is the commercialemployment. Choose the most appropriate model and explain in writing why this model is selected as the most appropriatemodel. Consider both goodness-of-fit and coefficient significance
- 1. The estimation of the rise and fall of river at any given point on the river during the course of flood event. a. Regression Analysis b. Hydrograph c. Hyetograph d. Linear Regression Analysis 2. A steeper hydrograph curve indicates a. flow discharge indicates a lower movement of water. b. water discharge does not significantly affect in the hydrograph analysis c. flow dicharge indicates a faster movement of water. d. flow discharge indicates a normal movemet of water. 3. A zero correlation value means. a. value should be less than the extremes such as: -1 and 1. b. an uptrend slope c. a downtrend slope d. no linear relationship bet independent and dependent variable.Select an appropriate transformation, transform your data and perform a least-squares regression analysis on the transformed data to find a-hat and b-hat.a) Derive the equation that gives the relationship between depth and discharge. b) Compare these results with your Log-Log graph resultsCLOSED COMPASS TRAVERSE. Given in the accompanying sketch are the observed forward and back bearings of a closed compass traverse. Adjust the observed directions and tabulate values accordingly. Can you show the complete solution for this problem including the computation. Thank you
