EwEugImportTimeSeries
v1 v2 36 36 * The software takes the ratio of ‘observed’ to estimated value for the years where there are observations, log it, ln(Oi/Ei). Then we estimate a scaling factor, S, as, S = exp[sum(ln(Oi/Ei))/count(i)]. Each of the observations is then plotted on top of the estimated value as Oi / S. (Oi Observed parameter no i, Ei Estimated parameter no i ) 37 37 38 ** Using data type 2, you can force nutrient concentrations (see [[Ecosim parameters.htmEcosim parameters]] and links therein); parameters that affect trophic interactions through abiotic factors (see [[Forcing function.htmForcing function]] and [[Apply forcing function consumer.htmApply FF (consumer)]]) or primary production (see [[Apply forcing function primary.htmApply FF (primary producer)]]).38 ** Using data type 2, you can force nutrient concentrations (see [wiki:EwEugEcosimParameters Ecosim parameters] and links therein); parameters that affect trophic interactions through abiotic factors (see [wiki:EwEugForcingFunction Forcing function] and [wiki:EwEugApplyForcingFunctionConsumer Apply FF (consumer)]) or primary production (see [wiki:EwEugApplyForcingFunctionPrimaryProducer Apply FF (primary producer)]). 39 39 40 † Forcing catches enables [[Using Ecosim for Stock Reduction.htm Use of Ecosim for Stock Reduction Analysis]].40 † Forcing catches enables [wiki:EwEugUsingEcosimForStockReduction Use of Ecosim for Stock Reduction Analysis]. 41 41 42 42 How to import a time series data file 43 43 44 Important note.
