This commit adds test-cptreg.R with 44 new tests covering:
- cpt.reg() input validation (data types, penalty, method, dist, etc.)
- cpt.reg() methods (AMOC, PELT) and output options
- cpt.reg() handling of 3D array input (multiple time series)
- cpt.reg() minseglen warnings and errors
- check_data() validation and edge cases
- ChangepointRegression() dispatcher function
- CptReg_AMOC_Normal() and CptReg_PELT_Normal() shape validation
- BIC.envcpt() error handling
- AICweights() default method and weight calculation
- plot.envcpt() error handling
- Integration tests for cpt.reg with envcpt
These tests significantly increase coverage for the internal changepoint
regression functions that were previously lacking dedicated test coverage.
Note: Found typo in source code ("penelty" vs "penalty") - documented in test.

Added extensive tests covering: - AR(2) model detection and accuracy - Trend data handling - AR(1) + trend combination models - Manual and Hannan-Quinn penalty types - Shape parameter tests (fixed/estimated variance) - CptReg_PELT_Normal and CptReg_AMOC_Normal edge cases - ChangepointRegression with various parameters - check_data edge cases (minseglen, duplicate intercepts) - Minseglen boundary conditions - Tolerance parameter variations - 3D array input with different methods/penalties - Changepoint detection accuracy validation - Return object structure verification - envcpt model subset tests - BIC.envcpt and AICweights boundary testing - plot.envcpt type variations - Numerical stability (small/large variance, large mean) - Data size variations (minimum to 1000 observations) - Penalty comparison tests - Distribution parameter handling All 91+ tests pass (some additional tests run with NOT_CRAN=true)

Summary
This PR adds a new test file
test-cptreg.Rwith 44 comprehensive tests to increase code coverage for the changepoint regression functions.Tests Added:
cpt.reg() function (core changepoint regression):
check_data() function:
ChangepointRegression() function:
CptReg_AMOC_Normal() and CptReg_PELT_Normal():
BIC.envcpt() and AICweights():
plot.envcpt():
Notes:
"penelty"instead of"penalty"in error message (line 8 of CptReg.R) - documented in testTest Results:
All 44 tests pass:
