A categorical variable, which is also referred to as a nominal variable, is a type of variable that can have two or more groups, or categories, that can be assigned. There is no order to the categories that a variable can be assigned to. In other words, the categories cannot be put ...
Explain the difference between a discrete and a continuous variable. Discrete variables can assume _ (any value / only certain values) any value only certain values, but continuous variables can assuExplain what an independent variable is.Evaluate the following: ...
What is an independent variable in math? What is the constant of proportionality in the equation y = 5x? (4x + 4)(ax - 1) - x^2 + 4 In the expression above, a is a constant. If the expression is equivalent to bx, where b is a constant, what is the value of b? A) -5 ...
When you have a quantitative variable, it can be discrete or continuous. In broad terms, the difference between the two is the following: You count discrete data. You measurecontinuous data. Discrete variables can only take on specific values that you cannot subdivide. Frequently, discrete data ...
Note, even though a variable may discrete, if the variable takes on enough different values, it is often treated as continuous. For example, most analysts would treat the number of heart beats per minute as continuous even though it is a count. The main benefit of treating a discrete variab...
When people receive interval estimates of a continuous variable, they often fail to understand the meaning of an arbitrary placement of upper and lower bounds delimiting a section of the underlying bell-shaped probability distribution. They often seem to think that all outcomes within an uncertainty ...
Regression is a simple, common, and highly useful data analysis technique, often colloquially referred to as "fitting a line." In its simplest form, regression fits a straight line between a one variable (feature) and another (label). In more complicated forms, regression can find non-linear...
In the regression model y = B0+ B1x1+ B3(x1xD1)+u, where x1 is a continuous variable and D1 is a binary variable, what does B3 indicate? Consider simple regression equation: y_i = \beta _0 + \beta _1x_i + e_i a. Derive R^2 b. What d...
latent trait analysis, latent profile analysis, and latent class analysis. Which model is ultimately used depends on whether the manifest variables are continuous or categorical, and whether the latent variables are continuous or categorical
A real asset is a tangible investment, such as gold, real estate, or oil, that has an intrinsic value due to its substance and physical properties.
