Example 2:
Repeat example 1 (using the same data) for logarithmic, exponential, and power
curve fits. The table below gives you the starting execution label and the results (the
correlation and regression coefficients and the
x
– and
y
– estimates) for each type of
curve. You will need to reenter the data values each time you run the program for a
different curve fit.
Normal and Inverse–Normal Distributions
Normal distribution is frequently used to model the behavior of random variation
about a mean. This model assumes that the sample distribution is symmetric about
the mean,
M,
with a standard deviation,
S
, and approximates the shape of the bell–
shaped curve shown below. Given a value
x
, this program calculates the probability
that a random selection from the sample data will have a higher value. This is
known as the upper tail area,
Q(x)
. This program also provides the inverse: given a
value
Q(x)
, the program calculates the corresponding value
x
.
