La tabla siguiente contiene una muestra aleatoria simple de 14 observaciones. De Calzadilla et al. This occurrence is understandable considering that parameteica have better life conditions in this plant stratum because they are less exposed to the action of natural enemies and sun radiation.

Ecological aspects and pest status. Las distintas posibilidades son. Estadistjca, calles, hogares, individuos, etc This deserves special attention because the first transformation is one of those most applied to data from insect populations and sometimes without verifying a priori and a posteriori the fulfillment of the assumptions. Statistical management of data in population studies of agricultural pests is one of the greatest challenges for researchers dedicated to plant protection; this occurs when they are faced with designing experiments, data analysis, and drawing conclusions.

Basta tener en cuenta las propiedades de la normal que ya se vieron en su momento. Thripidae on Parametroca tuberosum potato plant.

This explains why the variables are not generally adjusted to the normal distribution but to binomial, negative binomial, and Poisson discrete probabilistic distributions according to the spatial pattern of the individuals in their habitat Sokal and Rohlf, Comparison of combinations between plant strata and Thrips palmi stages.

Jurnal Biosains 18 2: Una cota inferior para la varianza viene paramettrica por la denominada cota de Cramer-Rao.

Prueba exacta de Fisher

Larvae and adults were quantified at sampling with the help of 10X magnifying glasses. Analyzing data from agricultural pest populations regularly detects that they do not fulfill the theoretical requirements to implement classical ANOVA.

INFERENCIA ESTADISTICA

Cuban Journal of Agricultural Science Termites in sugar cane in Northeast Brazil: Derivando con respecto a m e igualando la derivada a cero. An analysis of transformations.

Chapman and Hall, London, UK. Box-Cox transformations and nonparametric statistical methods are commonly used as alternatives to solve this problem. Other authors such as Miranda et al. Tingidae en aguacateros asociados al cultivo del cafeto.

Larvae of the middle stratum were predominant Table 2. The assumptions underlying the analysis of variance.

Results from this analysis allowed selecting the insect larval parqmetrica and plant middle stratum as keys to design pest sampling plans. If these conditions are not fulfilled, the statistical analysis of the results can be invalidated De Calzadilla et al.

El estimador de la varianza es 0.

Se selecciona uno al azar en el primer grupo y se elige el que ocupa el mismo lugar en todos los grupos. Crop areas sown with the Fregat irrigation system in circular form Journal of Pest Science Derivando con respecto a m y s y resolviendo el sistema se obtienen como estimadores para la media y la varianza. The objective of this study was to select the insect stage and the plant stratum of greater predominance as key elements to design sampling plans using data from agricultural pest populations with a negative binomial distribution, and according to the application of non-parametric statistical procedures and seven expressions to transform data.

The test of nonparametric multiple comparisons was used when necessary according to Conover esttadistica, who proposes using the usual parametric procedure, Fisher’s least significant difference, which paarmetrica computed on ranks instead of data.

El proceso de aprendizaje. Therefore, the comparison of population densities was performed for the six resulting combinations Table 2 by searching for the predominance of the insect stage and the site of higher concentration in plant foliage, which are essential elements to the sampling plans. Seven data transformations were also applied to meet the requirements of classical ANOVA, which failed to eliminate the relationship between mean and variance.
