(Regression Analysis)
Consider the simple linear regression model (I) and the
corresponding scatter plot with the covariates XX (x-axis) vs
residuals (y-axis). What model assumption violations can be
diagnosed by this scatter plot?
Draw the ERD in Chen notation corresponding to the following
spec:
Sailors are identified by an sid, having a name, age, and
rating
Boats are identified by a bid and also have a name and a
color.
Sailors reserve boats on a given date.
Every sailor reserves a boat at some time
Problem 2: Plot the LST (y?axis) corresponding
to 10:00 AM versus months (x?axis) (consider the 21st day of each
month as the representative of each month) for Panama City Bay,
Florida.
. Draw a plot of the following set of data
and determine the linear regression equation. What is
the
value of the slope and
intercept? What is r and
R2? Are there any outlier
values? (15 points)

First, draw the state
machine for the following program. Then write the corresponding
Verilog behavioral code.
Input: X - 1 bit
number
Output: Z - 1 bit
number
Clock: clk (State will
change at positive edge of the clock)
Output will be equal
to one if Xn-2 Xn-1 Xn = 011 or
Xn-2 Xn-1 Xn = 101
