What does C mean in stats?
concordance
The C-statistic (sometimes called the “concordance” statistic or C-index) is a measure of goodness of fit for binary outcomes in a logistic regression model.
What does the little C mean in stats?
The complement of an event is the subset of outcomes in the sample space that are not in the event. A complement is itself an event. The complement of an event A is denoted as A c A^c Ac or A′.
How do you find C in statistics?
The c-statistic is equal to the AUC (area under the curve), and can also be calculated by taking all possible pairs of individuals consisting of one individual who experienced a positive outcome and one individual who experienced a negative outcome.
What does C stand for in math?
The latin small letter c is used in math to represent a variable or coefficient.
What does exponent C mean?
Small lower-case c as an exponent when a Universe of Discourse is understood generally represents complement relative to U. That seems to be almost certainly the meaning in what you write: (A∩B)∪Dc would be the collection of all things that are in either in both A and B, or else that are not in D, as Dc={x∈U∣x∉D}.
What is 5C3 in probability?

What is C in Step deviation method?
Solution: Applying the Standard Deviation Method, We take the assumed mean to A = 99, and here the width of each class(c) = 6. Classes.

What is the use of int stat in C?
stat() function in C. int stat(const char *path, struct stat *buf); stat() function is used to list properties of a file identified by path. It reads all file properties and dumps to buf structure. The function is defined in sys/stat.h header file. Here *path is a pointer to constant character pointing to file path.
How do you calculate the C-statistic?
The c-statistic is equal to the AUC (area under the curve), and can also be calculated by taking all possible pairs of individuals consisting of one individual who experienced a positive outcome and one individual who experienced a negative outcome.

C is generally used as the symbol for a constant (significantly used to denote the constant of integration). To show unequal constants, C can be subscripted with numbers. Also C in Roman Numeral denotes 100. C is also used as a symbol of Combinations in combinatorial mathematics.
What does the Little C mean in probability?
What does the little C mean in probability? P (AB) means the probability that events A and B occur. You could write it P (A∩B). The superscript c means “complement” and Ac means all outcomes not in A. Hereof, what does the little C mean in statistics?
