O Que é Parametro – As parameters, you can define variables and constants that occur in mathematical expressions, and their variability allows you to solve problems. In this way, parameters specify numerical representations of the vast amount of information obtained from the study of variables. Its calculation is usually done using an arithmetic formula developed in advance on the basis of data obtained from the population.

In the field of computer programming, the term argument is used very loosely to refer to an inherent property of a procedure.

When a mathematician begins to study a variable, he is faced with an infinite number of random numbers. Therefore, it is necessary to process this information in advance in order to reduce and organize it so that you can work in a simpler and more efficient way.

Although the concentration of the initial data in the parameters implies a partial loss of information, this can be compensated for by making comparisons between samples or allowing the data to be characterized.

Location measurements identify approximations that group most of the data together. There are two types of discrete parameters: centrally biased parameters (mean, mode, and median) and offcentral parameters (percentiles, deciles, and quartiles).

Dispersion measures, on the other hand, are used to summarize the distribution of data. The problem with these parameters is that they are insufficient because they oversimplify the information, so it is necessary to monitor other auxiliary parameters that provide information about the heterogeneity of the data.

The most important dispersion parameters are: variance, typical deviation, coefficient of variation and range

Finally, the shape parameter represents how the histogram of the data is displayed, with the most common representation being a Gaussian curve. The coefficients of asymmetry and kurtosis are also noteworthy.

On the other hand, there are statistical parameters for specific purposes, such as the Gini index to measure inequality.

With these techniques, we can use random sample information to draw conclusions about the population of interest. The most important and most commonly used statistical inference techniques are: estimation and hypothesis testing.

3 Basic Concepts Parameters are numerical quantities that describe general characteristics and are usually unknown. It is usually represented by a Greek letter, e.g. Estimators are functions that we use to estimate sample values ​​of population parameters. In general, estimators are denoted by Greek letters with circumflex accents: etc. The estimated value is the value obtained by the estimator.

4 Sampling error is the difference between the sample result and the actual result of the population; such errors are the result of random sampling fluctuations. A non-sampling error occurs when sample data is collected, recorded, or analyzed incorrectly. For example: data selection using biased samples, use of faulty measuring instruments, or faulty data recording.

6 The estimation of the estimated parameters can be carried out using point estimation or interval estimation. Point estimate: A single value is used to estimate a population parameter. Confidence interval (or range estimate): is the range of values ​​(or range) used to estimate the true value of a population parameter.

8 Example 1: Your company sells sportswear and equipment online. To plan clothing, you need to gather data on the physical characteristics of different types of customers. The weights (kg) of the 24 male runners are shown below. Suppose these runners can be considered a random sample of all male potential customers.

The point estimator generates a single number as a parameter estimate. This process does not allow us to assess the likely severity of our mistakes. Confidence intervals tell us how accurate the score estimates are. Confidence intervals are obtained from the sampling distribution of its estimator.

The sampling distribution of the estimator is the distribution of all values ​​of the estimator when all possible samples of size n are drawn from the same population.

The signal is created by a combination of hand movements of a certain shape in a certain place, which can be a part of the body or a body in the space in front of it. They can be compared to phonemes, and sometimes to morphemes of hand articulation, which are called parameters.

These are hand shapes that can come from writing (handwritten alphabet) or other shapes made with the dominant hand (right hand for right-handers) or both hands of the sender or signer. LEARN, ORANGE and ADORAR have the same hand shape.

This is where the dominant hand of the setup is centered and may be touching a body part or be in neutral vertical (from the center of the body to the head) and horizontal (in front of the emitter) space. The WORK, PLAY, FIX signs are placed on the neutral space, and the FORGET, LEARN, and THINK signs are placed on the forehead.

Signals may or may not have movement. The signs listed above have movement except PENSAR which has no movement like the KNEELING and STAND-UP signs.

Constellations can have a direction, and the reversal of that direction can mean opposition, opposites, or ideas of personal number compatibility, such as desirable and unwanted signs of the zodiac; coming and going.

Many marks, in addition to the four parameters listed above, also have facial and/or body expressions as distinguishing features in their configuration, such as the ALEGRE and SAD marks. There are slap marks like THIEF , SEXUAL ACT In this short article I will talk a bit about parameter types used in REST API requests and a simple usage example.

API parameters are variable parts of resources (routes). Specify the type of operation you want to perform on the resource. Each parameter has a name and a value type. Every time you want to build a REST API, you need to decide which parameters should appear in the endpoints of your API. Put simply, API parameters are options that can be passed along with an endpoint to influence the response.

There are four different types of parameters commonly documented and actually used in REST APIs. They are:

These parameters appear in request headers and are typically related to authorization such as tokens, session controls, and cookie data. This parameter type appears in any HTTP method (GET, POST, PUT, DELETE).

Query parameters are the most common parameter type. They appear at the end of the request URL with a question mark (

Also, they are not unique in the sense that they can be used to specify any parameter multiple times.

Path parameters are variable parts of the URL path. They are often used to point to a specific resource in a collection, such as a user identified by an ID. A URL can have multiple path parameters, each path parameter is marked with braces

They are in the body of the request and are used to send and receive data via the REST API. Someone said that this type is not a parameter, but I decided to include it in this list because it is often used in PUT and POST requests.

In this article, we saw how each type of parameter used in a REST API request works and how to use each one. While it sounds simple, it’s important to keep these concepts in mind when creating an API.
