a vector of the station identifiers on which to do the flow adjustment. |
Snames |
a vector of the response variables on which to do the flow adjustment. |
sig.level |
the alpha level of the test. If the attained p-value
of the test is less than |
A data frame of the requested trend tests having these columns:
Station |
the station identifier. |
Response |
the response variable name. |
Type |
the type of trend test. |
NumYears |

NumSeasons |
the number of seasons. Set to |
Nobs |
the number of observations used in the test. |
RepValue |
the representative value of the response variable. See
|
Trend |
the trend expressed as the average rate in Response units per year |
Trend.pct |
the trend expressed as the average rate in percent change per year |
P.value |
the attained p-value of the test. |
Trend.dir |
an indicator of the trend. |
The representative value is the median from a sample of the data taken to represent a reasonably uniform sampling over time and throughout the year. For the seasonal Kendall test, it is the median of the data, for the Tobit test, it is the median of the data sampled as for a seasonal Kendall test.
