Bootstrapping is a statistical method for estimating the sampling distribution of an estimator by sampling with replacement from the original sample, most often with the purpose of deriving robust estimates of standard errors and confidence intervals of a population parameter like a mean, median, proportion, odds ratio, correlation coefficient or regression coefficient.
Captain Jack Sparrow is the protagonist of the series, portrayed by Johnny Depp. First introduced in the film Pirates of the Caribbean: The Curse of the Black Pearl (2003), he later appears in the sequels Dead Man's Chest (2006), At World's End (2007), On Stranger Tides (2011), and Dead Men Tell No Tales (2017).

For example, a free offer or newsletter sign up form may only request an email address, whereas high value offers may have longer forms with more details required. They may also include a relevant image, animation or short video.
Synthetic data is "any production data applicable to a given situation that are not obtained by direct measurement" according to the McGraw-Hill Dictionary of Scientific and Technical Terms; where Craig S. Mullins, an expert in data management, defines production data as "information that is persistently stored and used by professionals to conduct business processes."
Whereas statistics and data analysis procedures generally yield their output in numeric or tabular form, graphical techniques allow such results to be displayed in some sort of pictorial form. They include plots such as scatter plots , histograms , probability plots , spaghetti plots , residual plots, box plots , block plots and biplots .
Data (US: / ˈ d æ ˈ t ə /; UK: / ˈ d eɪ ˈ t ə /) are individual facts, statistics, or items of information, often numeric. In a more technical sense, data are a set of values of qualitative or quantitative variables about one or more persons or objects, while a datum (singular of data) is a single value of a single variable.
In Bayesian statistics, a maximum a posteriori probability (MAP) estimate is an estimate of an unknown quantity, that equals the mode of the posterior distribution.The MAP can be used to obtain a point estimate of an unobserved quantity on the basis of empirical data.
When the null hypothesis is true, if it takes the form : =, and the underlying random variable is continuous, then the probability distribution of the p-value is uniform on the interval [0,1]. By contrast, if the alternative hypothesis is true, the distribution is dependent on sample size and the true value of the parameter being studied.
