Regression analysis is a True
tool for building
mathematical and
statistical models that
characterize relationships
between a dependent
variable and one or more
independent, or
explanatory, variables.
T/F
Simple Linear regression True
involves finding a linear
relationship between one
independent variable, X,
and one dependent
variable, Y. T/F
An increase in adjusted True
R2 indicates that the
regression model has
improved T/F
Multiple R is another True
name for the sample
correlation coefficient
An interaction occurs True
when the effect of one
variable is dependent on
another variable T/F
In regression analysis, False
dependent variable can
be of any type (ratio,
categorical, ordinal and
interval) T/F

Which one is true? D) all statements are true
a) R-squared is a measure
of the "fit" of the line to
the data
b) The value of R-squared
will be between 0 and 1.
c) the larger the value of
R Squared the better the
fit
D) All statements are true
One judgmental True
approach for forecasting
is historical analogy, in
which a forecast is
obtained through a
comparative analysis with
a previous situation T/F
The Delphi method is a True
popular forecasting
approach which uses a
panel of experts to
respond to a series of
questionnaires. T/F
Time series that do not True
have trend, season, or
cyclical effects but are
relatively constant and
exhibit only random
behavior are called
stationary time series. T/F
Cyclical effects are those False
that repeat at fixed
intervals of time, typically
a year, month, week, or
day. T/F
