May I have your minutes for my question below? I was doing linear regression and want to compare my models with a likelihood ratio test. However,
1. The likelihood ratio test lrtest()
seems not working for me. I mean, I did typing ?lrtest
and couldn't get any documentation in R.
Then, I moved to ANOVA(model1, model2, test ="LRT"). However, It gave me an error. "Error in UseMethod("anova"):no applicable method for 'anova' applied to an object of class "list" I used a data set of the iris as follows.

QUESTION
I'm working on a project for a clinic which runs OCR on some lab documents then parses the data and automates its entry into their lab system. The raw data is semi-structured enough that I can put it through a series of steps to extract the data I need in the order that I need. I'm starting to hit a wall from staring at it too long and would appreciate another set of eyes on it.
The process works like this:
- first pass over the raw text and extract ICD10 CODES using RegularExpressions which match the standard specification and boundaries that exist specifically to the lab document including potential artifacts from the OCR read.
- second pass that extract TEST CODES, which are unfortunately far more variable in terms of character composition. Note that I also have to force boundaries due to the way the document is formatted, the composition of the text, and due to OCR artifacts.
- After these passes I have the data organized in a list which I reorganize and group a certain way. That all works fine.
The regex I am using to extract TEST CODES follows:
(?<=•\s*|\.\s*|\s*)(?[A-Z0-9]{3,9})(?=\s*\||\sJ\s|\sj\s|\sI\s|\s\[\s|\s\]\s)
Two examples of actual data are below. In the first one I am matching all the test codes (the 4 digit numbers at the start of the line) in addition to matching 3 character groups at the end (GFR,A1C).
The second image looks ideal, with only the test codes being matched.
How can I not match the three character groups when my test code might indeed be three characters (of upper alpha and digit)?
