What is the differences between constant and proportional error?

A constant error is something that does not change as the variable you are observing changes. For example, a set of scales that are always 0.3kg off. No matter who is standing on them, they will always get a reading that is 0.3kg greater than their actual mass.
A proportional error changes as the variable you are observing changes, but more importantly it changes in a way that can be predicted.

What is the difference between systematic error and accidental error?
Systematic error is a constant or known:effects of the error are cumulativeerror is always positive or negativeAccidental error is a unavoidable error: effects of the error is compensationerror is equally like to be positive or negative
Which statistic estimates the error in a regression solution?
The mean sum of squares due to error: this is the sum of the squares of the differences between the observed values and the predicted values divided by the number of observations.
What is the difference between low percent error and high percent error?
The difference between low percent error and high percent error is one is low and the other is high
What is the difference between a bias and a random error?
Bias is systematic error. Random error is not.
What is the systematic error detection?
Systematic error is the difference between the actual value of what is being measured and the value you found. The results of systematic error are precise but not accurate.

How does sample size affect the size of your standard error?
The standard error should decrease as the sample size increases. For larger samples, the standard error is inversely proportional to the square root of the sample size.The standard error should decrease as the sample size increases.

What are the effects of sample size on sampling error?
The sampling error is inversely proportional to the square root of the sample size.

The mean sum of squares due to error: this is the sum of the squares of the differences between the observed values and the predicted values divided by the number of observations.
How can you avoid constant error?
By regular practice
What is along and digital control system?
A: The last time that i kept up with types of systems there were only three what is along?. Well anyhow type-0 system is one that requires a constant error signal to operate type-1 a constant rate of change of the controlled variable requires a constant error signal under steady state condition. type 1 is usually referred as servomechanism system. type-2 a constant acceleration of the control variable requires a constant error under steady state condition. type-2 sometimes is referred to as zero velocity error system
What is the differences between and the patches and the service packs?
There is a difference between patches and service packs. Service packs contain the complete part of the software being updated. Patches contain a small bit of information that will correct an error.
What are the differences between require once and include once in PHP?
They're completely identical except how they output errors. Include produces a warning, while Require produces a fatal error.
What kind of systematic errors are detected by varying the sample size?
I believe a varying sample size detects a constant error which is a type of systematic error.
