TDB

Secondary definition for alpha in the context of ggplot

Secondary definition for Cronbach's alpha

Could be useful to have an explanation about pivot functions pivot_longer() and pivot_wider(), linking to the definitions for long and wide.

Example or extended definition

in the context of backslashes creating literal versions of symbols that have a special meaning.

1. Add .Rmd
2. TBD

Definition of term "list" uses the term "container" (container data type) which links to C category in Glossary but definition for it doesn't exist yet.

Typo: "the conventional a t-test" should be "a conventional t-test"

Could be useful to define permutation tests and maybe link to Monte Carlo?

1. add Rmd
2. TBD

To be Added:

Propose: the number of observations that are free to vary to produce a known outcome

Basic example: If you run 5 people and ask them their age, and you know the mean age of those 5 people is 20.1, then four of those people can have any age but the 5th person must have a specific age to maintain the mean of 20.1. So the mean age here is the known outcome and four peoples age can vary freely (so your degrees of freedom is 4) but one person's age must be a specific number to maintain the known outcome.

Alternatively we could use something from the t-distribution and show how changing the df changes the probability of the outcome on the t-distribution.

1. Add .Rmd
2. TBD

Needs an example

Additional comment or example about using whitespace in APA write-up. e.g.

with whitespace: t(df) = t-value, p = p-value, d = d-value

without whitespace: t(df)=t-value, p=p-value, d=d-value

1. Rmd Needed
2. TBD

in the context of Shiny content

link to knit

explain how to remove NAs for calcs like mean, sd, cor

1. Add RMD
2. TBD

Typo: "noraml"

TBD

Suggested: "when two or more values/observations within a variable are identical and assume the same rank order value"

1. to add .Rmd file
2. TBD

Packages that are required to run another package. R should automatically install these for you when you install a new package.

Needs an example

Define formula in the sense of R's object type?

Overview of joins and link to :

• binding joins
• filtering joins
• mutating joins

Also separate entries for semi_join, anti_join, left_join, right_join, inner_join, outer_join that link to their join type.

Link from "alpha" also

See https://courses.lumenlearning.com/waymakerintermediatealgebra/chapter/read-writing-scientific-notation-2/

link to Ch 4 in ADS

Would be good to include maybe a paper on detecting outliers as well

TBD - add a section on what is a boolean expression and give examples.

1. add rmd
2. TBD

TBD - would be good to add something about conflicts in function names

Needs an example

Needs more detail and links to papers/resources

Example needs explanatory text

Might be an idea to have a function that displays the definition of a word in the actual body of text in a paragraph, rather than the word. Say for example:

"Degrees of Freedom is defined as r glossary_show_definition("degrees of freedom")

Which would knit as:

"Degrees of Freedom is defined as The number of observations that are free to vary to produce a known outcome."

though might need to put a tolower() around it. That way people would only need to update the definition in the glossary and it would update in other places it is used and remove any inconsistencies. Might not be frequently used but could be handy.

In the context of Shiny content

A description of what a model does/its aims. Could link to examples like glm and glmm.

Would be useful to define the environment - maybe linking to definitions for objects and variables.

ToBeAdded.

Suggestion:

Data Visualisation is the skill of creating and interpreting plots and figures from data.

TBD - would be good to add something about the idea of the library and loading packages into the library.

1. Add .Rmd
2. TBD
