Local treatments are those that destroy, remove, or control the cancer cells in a particular area. Surgery and radiation are both local treatments. Systemic treatments are those that destroy the cancer cells throughout the body.

What is a local anesthetic?
Local anesthesia refers to using a drug called an anesthetic to temporarily numb a small area of your body. Your doctor might use a local anesthetic before doing a minor procedure, such as a skin biopsy. You might also receive local anesthesia before a dental procedure, such as a tooth extraction.

Systemic means affecting the entire body, rather than a single organ or body part. For example, systemic disorders, such as high blood pressure, or systemic diseases, such as the flu, affect the entire body.
General definition
In the terminology from the potential outcomes framework, Y i ( d i ) {\displaystyle Y_ {i} (d_ {i})} denotes the potential outcome of subject i {\displaystyle i} , where d i {\displaystyle d_ {i}} is the binary indicator of subject i {\displaystyle i} ’s treatment status.
Identification
The I T T {\displaystyle ITT} measures the average effect of experimental assignment on outcomes without accounting for the proportion of the group that was actually treated (i.e. average of those assigned to treatment minus the average of those assigned to control). In experiments with full compliance, the I T T = A T E {\displaystyle ITT=ATE} .
Application: hypothetical schedule of potential outcome under two-sided noncompliance
The table below lays out the hypothetical schedule of potential outcomes under two-sided noncompliance.
Others: LATE in instrumental variable framework
We can also think of LATE through an IV framework.
Generalizing LATE
The primary goal of running an experiment is to obtain causal leverage, and it does so by randomly assigning subjects to experimental conditions, which sets it apart from observational studies. In an experiment with perfect compliance, the average treatment effect can be obtained easily.
What is local treatment?
Local treatments refer to the application of termite control products to a specific area or areas. Several products are used for local termite treatment but they are not equal. Local treatment products and methods vary widely in efficacy, toxicity, and cost.
Can termite treatments be sold?
Even local termite treatment products that are proven to achieve full elimination of the termite colonies they are applied to, cannot be sold or marketed as alternatives to fumigation.
How to find local average treatment effect?
10 Things to Know About the Local Average Treatment Effect 1 Abstract 2 1 What it is 3 2 With one-sided noncompliance you need to satisfy an exclusion restriction to estimate the LATE 4 3 With two-sided noncompliance the LATE can be estimated assuming both the exclusion restriction and a “no defiers” assumption 5 4 The LATE is an instrumental variables estimate 6 5 The LATE only estimates the treatment effect for the compliers 7 6 A different instrument will give a different LATE 8 7 The LATE estimate is always larger than the ITT estimate 9 8 You can use LATE for “encouragement” designs 10 9 You can use the LATE to implement downstream experiments 11 10 Addressing partial compliance can be complicated
What happens when a subject does not receive the treatment to which they were assigned?
1 What it is. When subjects do not receive the treatment to which they were assigned, the experimenter faces a “noncompliance” problem. Some subjects may need the treatment so badly that they will always take up treatment, irrespective of whether they are assigned to the treatment or to the control group.
Do subjects take treatment even if they are assigned to the treatment group?
Other subjects may not take the treatment even if they are assigned to the treatment group: the “Never-Takers”. Some subjects are “Compliers”. These are the subjects that do what they are supposed to do: they are treated when assigned to the treatment group, and they are not treated when they are assigned to the control group.
Overview
The local average treatment effect (LATE), also known as the complier average causal effect (CACE), was first introduced into the econometrics literature by Guido W. Imbens and Joshua D. Angrist in 1994. It is the treatment effect for the subset of the sample that takes the treatment if and only if they were assigned to the treatment, otherwise known as the compliers. It is not to be confused with the average treatment effect (ATE), which is the average subject-level treatment e…
General definition
The typical terminology of the Rubin causal model with units indexed and binary treatment indicator for unit i, is used. Potential outcomes denote the potential outcome of unit i under treatment .
In an ideal experiment, all subjects assigned to treatment are treated, while those that are assigned to control will remain untreated. In reality, however, the compliance rate is often imperf…
Potential outcome framework
The treatment effect for subject is . Both and for the same subject can never be observed simultaneously. At any given time, only a subject in its treated or untreated state can be observed.
Through random assignment, the expected untreated potential outcome of the control group is the same as that of the treatment group, and the expected treated potential outcome of treatment group is the same as that of the control group. The random assignment assumption thus allow…

The , whereby
The measures the average effect of experimental assignment on outcomes without accounting for the proportion of the group that was actually treated (i.e. an average of those assigned to treatment minus the average of those assigned to control). In experiments with full compliance, the .
Others: LATE in instrumental variable framework
LATE can be thought of through an IV framework. Treatment assignment is the instrument that drives the causal effect on outcome through the variable of interest , such that only influences through the endogenous variable , and through no other path. This would produce the treatment effect for compliers.
In addition to the potential outcomes framework mentioned above, LATE can also be estimated …
Generalizing LATE
The primary goal of running an experiment is to obtain causal leverage, and it does so by randomly assigning subjects to experimental conditions, which sets it apart from observational studies. In an experiment with perfect compliance, the average treatment effect can be obtained easily. However, many experiments are likely to experience either one-sided or two-sided non-compliance. In the presence of non-compliance, the ATE can no longer be recovered. Instead, w…
