critical_r

Calculates critical value of Pearson correlation coefficient
for a selected alpha.

Provides novel dendroclimatological methods, primarily used by the
Tree-ring research community. There are four core functions. The first one is
daily_response(), which finds the optimal sequence of days that are related
to one or more tree-ring proxy records. Similar function is daily_response_seascorr(),
which implements partial correlations in the analysis of daily response functions.
For the enthusiast of monthly data, there is monthly_response() function.
The last core function is compare_methods(), which effectively compares several
linear and nonlinear regression algorithms on the task of climate reconstruction.
