Binary logistic regression is a logistic regression that applies to binary (0,1) variables (e.g. live or die, fail or pass...). Binary logistic regression is used to predict and model 0,1 problems in medicine, BI and many more fields. The reason logistic regression is preferred by many researchers is that it allows one to see the effect every variable has on the model in contrast to black boxed models such as neural networks.
A binary number is a number expressed in base-2 numeral system, which uses only two digits: 0 and 1. When you say "of eight," it is unclear what you are referring to. If you are asking about the digit 8 in binary, it is represented as 1000.
BCD-BinaryCodedDecimal->Binary equivalent of each decimalexpressed using 4 bits->For single digit decimal BCD is same as its binary.In BCD only first 10 binary numbers are valid.The remaining 5 are invalid. Gray code is an unweighed code. ex: G3=B3 G2=G3 XOR B2 G1=G2 XOR B1 G0=G1 XOR B0
Form of modulation that represents digital data as variations in the amplitude of a carrier wave Follow this link to get exact idea of Amplitude Shift Keying (ASK) http://www.circuitsgallery.com/2012/05/binary-amplitude-shift-keying-bask-or.html
The result of the expression "13 and 25" would be 9. This is because the "and" operator performs a bitwise AND operation on the binary representations of the numbers 13 and 25, which results in 9.
Deconstructionist theory is a type of conflict theory that focuses on revealing the underlying power dynamics and assumptions in society's structures, language, and discourse. It aims to challenge traditional ways of thinking and disrupt binary oppositions to uncover multiple meanings and perspectives.
The logistic regression "Supervised machine learning" algorithm can be used to forecast the likelihood of a specific class or occurrence. It is used when the result is binary or dichotomous, and the data can be separated linearly. Logistic regression is usually used to solve problems involving classification models.

Using real-world data from a data set, a statistical analysis method known as logistic regression predicts a binary outcome, such as yes or no. A logistic regression model forecasts a dependent data variable by examining the correlation between one or more existing independent variables. Please visit for more information 1stepgrow.
In cases wherethe dependent variable can take any numerical value for a given set of independent variables multiple regression is used.But in cases when the dependent variable is qualitative(dichotomous,polytomous)then logistic regression is used.In Multiple regression the dependent variable is assumed to follow normal distribution but in case of logistic regression the dependent variablefollows bernoulli distribution(if dichotomous) which means it will be only0 or 1.
in general regression model the dependent variable is continuous and independent variable is discrete type. in genral regression model the variables are linearly related. in logistic regression model the response varaible must be categorical type. the relation ship between the response and explonatory variables is non-linear.
The term "Logistic regression" is referring to the graph of analysis in predictions. There are variables involved and explain probabilities that are a hypothesis of the dependent variable, which is the one being applied to a future prediction.
If your dependent variable is dummy coded (binary) then you must use a logistic regression for you analysis. There are two types; logit and probit. Both types return very similar results and your decision on which to use is based on personal preference and discipline standards. Economics and marketing tend to use probit while sociology tends to use logit.
It all depends on what data set you're working with. There a quite a number of different regression analysis models that range the gambit of all functions you can think of. Obviously some are more useful than others. Logistic regression is extremely useful for population modelling because population growth follows a logistic curve. The final goal for any regression analysis is to have a mathematical function that most closely fits your data, so advantages and disadvantages depend entirely upon that.
In fitting a logistic regression, as in applying any statistic method, the required sample size depends on the level of dispersion in the population and the quality of the statistics that you are prepared to accept. Usually there will be some information available somewhere (in the literature, say, or from colleagues) suggesting what level of variability to expect in data that is collected. This can be used to simulate some data sets and the logistic regression results that would arise from them. By varying the sizes of the data sets you can make a judgement. Once you have collected your first sample and fit the actual logistic regression to it you will have a much better idea how much data is actually required for useful estimates.

A subsection of the question above. You have to demonstrate an understanding of what the typical goals of a logistic regression are (classification, prediction, etc.) and bring up a few examples and use cases.
