Multiple Linear Regression A nursing instructor wishes to see whether a student's grade point average and age are related to the student's score on the state board nursing examination. She selects five students and obtains the following data. Student A B D E GPAX₁ 3.2 2.7 2.5 3.4 2.2 Age x₂ 22 27 24 28 23 State board score y 550 570 525 670 490 My Solutions > a) Refer to fitlm. From its output, determine the b0, b1, and b2. Do not simply enter the values but work with objects in MATLAB. You can also search How to get the p-value as an output of fitlm on MATLAB Answers. b) Predict a student's state board score who has a GPA of 3.0 and who is 25 years old. The multiple regression equation is y = bo+b₁x₁ + b2x2. c) Obtain the Coefficient of Determination (R²) from fitlm's output. Check LinearModel. d) Obtain the F-statistic using coefTest. Its value must be the same as that of fitlm with some discrepancy due to rounding off.

Each publication of an academic can be cited from other publications. To this academic The h-index value is calculated as follows. The total number of articles of that academic It has an index of h if each of them is cited at least. For example, a If there are 28 articles cited at least 28 times among the author's research articles, the author's h-index is 28. In order for the H-index to be 29, 29 or more of 29 articles must be cited. must have received. Accordingly, the number of citations for each of the N articles of an author varies from large to small. C code the program that calculates the researcher's h-index when given sequentially. Write in "C"language. The examples below show the number of citations received for each publication.
